I feel like there is a GPS joke somewhere here, but I can’t come up with it: Magenta color does not exist. Every color we see exists in the visible light spectrum except magenta. Our brain makes it up. https://medium.com/swlh/magenta-the-color-that-doesnt-exist-and-why-ec40a6348256
That’s not true that magenta is the only one. You can combine different wavelengths of light in all kinds of ways to “create” colors that can’t be described by a single wavelength. Edit: I see that the article says this, if you read down a bit…
Well. The difference here is that brown is a shade of orange, so it does have a wavelength (orange) at lower intensity. Magenta is purely made up. Is it the only one ? I don’t know. A BBC video said so. Here is an interesting cultural color difference. Russians have 7 colors in a rainbow. This is only because they have different names for light blue and dark blue while in English it’s all shades of blue. I’m guessing that there are many cultures/languages that have different number of colors in a rainbow than English
So do we, didn't everybody learn "Roy G. Biv"* in grade school science classes? *Red, orange, yellow, green, blue, indigo, violet.
I learned "Bad Boys Rape Our Young Girls While Violet Gives Willingly". That ought to wake up the EEs on here. It is now obviously politically incorrect. Anyone know what they use now? -Skip
As our brains can only "see" red, green, and blue, all other colors are created in our brain by a whatever combination of cone receptor stimulation is occurring from what wavelength of light we see. Since our brain is creating all other colors for our mind, is what I think purple looks like the same as what you think it looks like? What blew me away is that there is no "white". "White is what our mind interprets when we see all the colors of the rainbow combined. (or combining Red, Green, Blue will also do it).
As an art student we learned Red ,yellow ,Blue were the primary colors. White is a tint and Black is a shade. Both not considered colors. We had to paint color wheels using primary on to secondary and ternary colors.
No. I didn’t. But that don’t mean it wasn’t taught. EDIT: We’ll gee, the mnemonics abound. Didn’t learn any of them. Still don’t mean they weren’t taught. Maybe I was just a BS. Bad Student
I thought white was the absence of any color and black was all of them at once. Actually I didn’t think it independently, I learned it somewhere, sometime that I don’t remember when and where.
That's what I thought, even after they tried to teach me differently in elementary school. But it's not true. Here is an explanation: https://www.adobe.com/creativecloud/design/discover/is-black-a-color.html
Another way to look at it is to pass white light through a prizm. It will split the light into all of the colors. Which means white light is composed of all of the colors.
You're both right. Creating white or black can be done either by adding or removing color depending on the medium. It's the opposite if you're talking about light vs a solid medium. It's called additive or subtractive color. With additive color, all colors together make white, like an LCD screen. With subtractive, as you remove all color, you get white, like when printing with ink.
You must not live in the south. Any part of your house painted black in the summer sun will heat and degrade before your eyes.
That works up here north of the Mason-Dixon Line too. Doesn’t even need to be black, just dark. The navy blue pair on our front door is great in winter… not so great in summer.
In one of the quaint seaside towns near me in CT, a guy in the town historical district wanted to do some renovations to a historic home, but one neighbor objected and the town zoning board denied him. He retaliated by painting the entire house gloss black, annoying the neighbor and the zoning board... but there were no laws prohibiting it. I don't know how it ended.
No visible magenta is what happens when there's a GPS failure. Also known the day Cirrus pilots have a simultaneous Chute pull.
