What causes purple lighting?

Why Is My Alexa Flashing Purple BOWLING GREEN, Ky. – No, it’s not for Halloween and it’s not to reduce light pollution, the purple street lights are actually a manufacturing error. People have come up with some crazy theories about the strangely colored lighting. From people saying it makes those who have been vaccinated against COVID-19 glow in the dark to a theory that purple light is better for the environment.

While the theories are endless and quite creative, the story is much less exciting than warding off vampires.
White LED light is made up of all of the colors in the rainbow, when one color is removed, such as green, it leaves red and blue light which mix and make purple.
Bowling Green Municipal Utilities’ Christy Twyman says she’s not exactly sure what caused the manufacturing error.

“They either have a chip that has gone bad in them or it’s a film on top of the lamp that’s controlling the color temperature that comes out and so they appear purple. And there’s all kinds of stories about why they’re out there. Some high schools really like them.

Is purple lightning a thing?

Why Is Our Lightning Purple? | Museum of Science, Boston The indoor sparks we create in our Theater of Electricity are purple, and visitors often ask what causes the color. We explore the reasons behind different shades of lightning, including atmospheric composition, humidity, and temperature.

This Pulsar podcast is brought to you by #MOSatHome. We ask questions submitted by listeners, so if you have a question you’d like us to ask an expert, send it to us at [email protected]. ERIC: From the Museum of Science in Boston, this is Pulsar, a podcast where we answer our favorite visitor questions.

I’m your host, Eric. And one of my favorite things about my job is presenting a lightning show in our Thomson Theater of Electricity. It has the world’s largest Van de Graaff generator, musical Tesla coils, and it inspires some great questions. One of the most common we get after a show is: why is your lightning purple? Joining me to dig into this question is a fellow zapper, Becca from our education team.

Becca, thanks for joining me. BECCA: Thanks for having me here, Eric. ERIC: So the first time I got this question, I had some guesses. But it’s my favorite kind of question. Because by researching the answer, I learned a ton. BECCA: Yes, this question is one that we get all the time. And it’s one that there isn’t a really good clear cut answer to, but I still love to talk about it.

ERIC: Yeah, there’s a whole lot going on. And it’s not like other questions where we have a simple answer. Honestly, sometimes that’s the most satisfying when you can be like: that’s the biggest animal. But it’s complicated. This one’s really complicated.

So let’s just start with what lightning actually is.
BECCA: Sure.
So lightning essentially is just when charges get separated and come back together.
And in doing so they end up heating the air where these charges get put back together to pretty extreme temperatures.
Up to 50,000 degrees Fahrenheit, maybe even more.

And so it is really cool that it creates this amazing light, this flash that we see. Of course, it can be a little bit different depending on the conditions. ERIC: Yes. So we explained that in the show: what lighting is. What we’re seeing is light from superheated air.

And the color of that light depends on the air, really. BECCA: Yeah, there are so many factors that really go into what produces a certain color of lightning. And one of those conditions is what is in the air because air is made up of different things, different elements, pieces of dust or moisture in the air.

And depending on where you are, that may be different. And so having lightning kind of going through this one spot of air may have it look a little bit different, just depending on what’s going on. ERIC: Yeah, there’s no such thing as pure air because air is a mixture of gases.

The average across the Earth’s atmosphere is like 70% nitrogen, 20-something percent oxygen, but there’s carbon dioxide, there’s argon, there’s a bunch of other gases, there can be more of some in certain places, there can be moisture in the air, there can be dust in the air.
It really depends on what the air is made of, and what’s in the air.

And our indoor lighting is the same thing as a lightning bolt outside in a storm. It’s just smaller, and it’s going through air. But it’s indoor air. So our air is more controlled than in a storm. BECCA: Yeah, we definitely control our humidity quite a bit.

So having a little bit less moisture in the air inside will cause our lightning to be so specifically consistent in that it’s always kind of purple. And that’s one of the questions that we get all the time. But it also has to do a lot with kind of how close you are to the lightning. Since light moves through air, the further you are away, the more air it has to go through.

The closer you are to the lightning, the less air has to go through and often will appear more white if you’re really close. I know Eric, you probably have experienced this too. But when we are in the cage during the presentation in our Theater of Electricity, the lightning appears white because we’re actually right next to it.

But further away in the audience, it appears a little bit more purple because that light has gone through more air to get to your eyes. ERIC: Yeah, so it’s the same as looking at a sunset. The sun looks like a different color because the sunlight has to go through more air. Some of the light colors get separated out so that sunset sun looks more red.

The same thing with lightning, even a couple feet of air can take away some of the colors and affect its appearance. BECCA: Yeah, absolutely, it can definitely change the way that that light is hitting our eyes, it can bend it in a way that we end up getting different colors.

Another reason why people have seen pink or green lightning before is because it often gets bent by, really specifically, snow in the air.
And that snow can cause that light to bend in ways that really no other gases can.
So snow is sort of important to be able to get those really cool colors.
ERIC: Yeah, it’s all about your viewing conditions, what kind of air you’re looking through how much air you’re looking through what’s in the air, all that stuff adds up.

And it makes it even harder because everybody’s eyes are different. And cameras are different. I mean, when I was researching this, I saw plenty of things on the internet that said if you take a picture of a lightning bolt with film versus digital, it comes out different somewhat.

Sometimes it can look more yellow or brown depending on your camera settings. BECCA: Yeah, and even, it might look different to each human in the exact same location, just depending on how each human is able to perceive color. ERIC: So lightning out in a storm, it can look white. If you see a lightning bolt it can look blue, maybe purple.

There’s some colors that are more rare. Like you said, maybe snow lightning can look a little bit more green. But some reddish or orange or yellow lightning tends to be associated with volcanoes, which I know you’re just really excited to talk about today.

BECCA: Absolutely. I love volcanoes. So combining two of my favorite subjects is excellent. I love this question about volcanic lightning, because it’s something that we often don’t think about. Usually people associate it with, maybe there’s a storm. But actually, the volcanoes themselves in their eruptions can create lightning.

They occur when there’s a really large ash cloud, all of these sort of small particles of kind of cooled, volcanic, well, magma when it comes out, comes out in a big column, because it’s being sort of ejected all at once. And in that column, there’s a lot of ash that tends to rub against other particles of ash.

And in doing so it separates the charges within this column, causing lightning to actually form through the entire column, but also even going outside the column to really anywhere else that can sort of rebalance those charges. And because there’s so much ash, and often so much dust and dirt, inside this column, all of those particles get heated too, and they can burn off, which is why that lightning can look a little bit more red, and a little bit more orange and yellow.

Also, there’s just different gases coming out of the volcano. You get a lot of sulfur dioxide, and several other pretty intense gases that cause this lightning to look so different, but so cool. ERIC: So it’s caused by a lot of the same things that storm lightning is caused by with droplets kind of rubbing up against each other or separating charge.

It’s the same thing we do in our theater on a much smaller scale with our machinery.
And it can happen in a volcano with all that ash.
But the conditions are way different because you have all these volcanic gases, you have the dust, you have the really distinct lightning bolts that are like no other colors anywhere else in the world.

BECCA: Absolutely. And that’s why a lot of volcanoes have been correlated with sort of other deities in mythology because of these intense bits of power and energy coming out of them. Not only are they impressive on their own, but when they create their own lightning, well, that’s just another layer on top of it.

ERIC: Well Becca, thanks so much for chatting about different colored lightning. BECCA: Of course. Thank you. This was so fun. ERIC: On your next visit to the Museum of Science, don’t miss our daily lightning shows. check for the daily schedule. And while you’re at home, you can take a virtual tour of the inside of our 30 foot Van de Graaff generator in our video series.

Until next time, keep asking questions. Theme song by Destin Heilman : Why Is Our Lightning Purple? | Museum of Science, Boston

What is the main message of the color purple?

Legacy – The Color Purple movingly depicts the growing up and self-realization of Celie, who overcomes oppression and abuse to find fulfillment and independence. The novel also addresses gender equality, Walker’s best-known work, The Color Purple received widespread critical acclaim, though it was not without critics, many of whom objected to its explicit language and sexual content.

In 1985 Steven Spielberg directed an acclaimed film adaptation of the book; it featured Whoopi Goldberg (Celie), Danny Glover (Albert), and Oprah Winfrey (Sofia).
The Color Purple was also adapted for the theatre, and the first Broadway production premiered in 2005.

What the LED light colors mean?

The difference between LED color temperatures is one of the most important things to know when installing new fixtures for a home or business. Let’s get the biggest point out of the way first – lights that run the same wattage and output the same lumen count can look wildly different depending on their color temperatures.

And this difference can extend to the biological level, as our brains are configured to respond to certain colors of light in profound ways.
If the wrong fixtures are placed in the bedroom, for instance, it can keep someone up late into the night, even when they want to sleep.
The same holds true for lighting artwork, cabinet lighting or even recessed general lighting applications.

Clearly, color temperature makes a big impact. Why Is My Alexa Flashing Purple So, exactly what is color temperature? First, a definition of what color temperature is. Although there is a lengthy history behind the term, involving experiments by 18th-century physicists, there’s a simple way to put it. Imagine a piece of black metal, the size or shape is unimportant.

To make it easy, consider a metal filament inside a light bulb.
As this black filament is heated, it glows, and as it increases in temperature, it begins glowing red, to orange, to yellow, to white and then finally blue at extremely high temperatures.
When a lighting professional refers to color temperature, they are really referring to the color this piece of black metal glows at a given temperature (measured in Kelvin).

Here’s a quick look at where these color temperatures fall on the scale:

1700K – the dull glow of a match flame
1900K – the steady light of a candle
2700K – warm, incandescent fixtures
3000K – the sun at sunset or sunrise
3500K – bright white, the setting for most fluorescent fixtures
5500K – daylight during a sunny day
6500K – daylight during a cloudy day, also the setting for most computer monitors
7500K – the coolest setting for most fluorescent lights

The lower the color temperature, the warmer the light will appear, or the redder it will appear. The higher the temperature, the cooler the light will appear, or the bluer it will look. In the residential and commercial lighting world, almost all fixtures will land somewhere between 2000K and 6000K. Perhaps the two most common color temperatures are 2700K and 3500K, as warm fixtures dominate residential settings. But cool fixtures have their purpose as well, and primarily in the commercial and industrial spheres. The reasons for this are aesthetic and biological in nature. Warm or cool? There isn’t too much controversy over what fixture should be used where. In general, warmer fixtures are preferred in most residential settings, and most homeowners prefer them. In commercial and industrial settings, cooler fixtures work better, and workers tend to prefer them in this setting. But why are warm fixtures better for residential installations, and cooler fixtures for commercial environments? This is where biology plays an important role. In the presence of bright white and cool fixtures, the body releases serotonin, a neurotransmitter that usually makes people feel more alert. This response is why sunlight can make someone feel more awake and active, and why it’s hard to fall asleep after staring into a computer monitor for a while. When those blue or white hues are absent, the body releases melatonin, a hormone that helps configure the circadian rhythm (the natural wake-sleep rhythm of the body) and encourages sleepiness. At night and at sunset, blue and bright white light are absent, sending the body into a sleepy state. There are some obvious applications of color temperature that can be derived from biology. Incandescent lights or warm LED lights encourage the release of melatonin, while fluorescent or cooler LED lights encourage the release of serotonin. That’s why warmer fixtures are reserved for most residential applications, like the bedroom or living room. In these settings, the warm light helps people relax and wind down for sleep. The only places where white or cooler lights are typically preferred are in the kitchen and bathroom. Here, people look for the higher contrast and better color rendering that neutral and cool fixtures offer. Some homeowners install cooler fixtures in their bedrooms to read by, as cool fixtures contrast well with the paper used in books. A few homeowners even prefer cooler LED fixtures for general bedroom lighting, as it helps them wake up in the morning. Warm fixtures are still preferred in some commercial settings, particularly lobby and reception areas, and for businesses like restaurants and hotels. In general, any business that needs to make its customers feel comfortable will need warm fixtures in some areas. However, cooler fixtures are needed in any setting where productivity and high contrast are needed. The single biggest application of cool LEDs is in office buildings, where bluer light can help boost worker productivity. A 2016 study published by The American Academy of Sleep Medicine confirms this. In that study, researchers exposed test subjects to 30 minutes of bright blue light, and then had them engage in cognitive testing. What researchers found was that those exposed to the blue light displayed faster reaction times and better scores on knowledge tests. In short, blue light is a brain booster. And its effects last nearly an hour following exposure, so the right fixture in an office building can magnify performance across the board. Blue and bright white light is almost always the standard in industrial properties like warehouses and manufacturing facilities. This is partly because workers in these facilities need to remain alert at all times. Another reason is because white light is the best at creating contrast between colors, and because it renders color better than warm fixtures. This isn’t just for productivity or aesthetic reasons. It may also be a safety issue. Warning signage and safety gear is usually colored orange, and under warm fixtures, it’s harder to pick this out. With bright white fixtures, it’s much easier to see another worker in an orange safety vest, or signage warning about work crews nearby. It Comes Down to Choice In the end, property owners have the final say regarding what color temperature to settle on. The answer will be different, depending on what mood the fixtures need to evoke, and what purpose the fixtures are intended for. And there’s no need to just pick one color temperature for an entire property. Warm fixtures can be installed in one room, and cool fixtures in another. And with emerging lighting technologies like LEDs, energy efficient options are available throughout the spectrum. All a home or business owner needs is a plan to get the configuration they want, and an experienced lighting firm can assist with that as well.
