I still want to know why red, blue, and YELLOW are the primary colors most of us learn about in grade school, when red, blue, and green are the primary additive colors. It isn’t like cyan, magenta, and yellow match up with this. How do we get orange for example? So curious

I’m an educator by day and an artist on the side. I used to teach my 6th graders a unit on light and pigment. I’d tape diffraction grating to the output lens of my overhead projector and create a narrow “beam” with paper or books (anything opaque) on the platform to project the spectrum. We’d pass things through the spectrum (or just walk through it) and observe. Had KZfaq been around, your video would have been a great resource and home reference (and a different voice). With your permission, I would like to share this on my art page, please.

What would result from mixing yellow and blue pigments? A quiz from an online class says green light will show, but if we start with blue, green, and red light, and the blue light is removed from the yellow pigment, and the green and red lights are removed from the blue pigment, would that not create black?

@simperingham 3 жыл бұрын

Pay attention to which pigments you are using (especially the blue). If the blue is halfway to cyan, you’ll get a dark green, not a “true” green.

@marxman1010 2 жыл бұрын

In fact, CMY is just another model like RGB, just colors chosen as the base colors of pigments. The subtractive model means absorption of light comparing to the light itself. So it is improper to say CMY is subtractive model. RGB can also be explained in subtractive way. For example Red absorbs Green and Blue. But light can't be explained in subtractive way. Therefore, color of light depends on additive model, and color of pigments depends on subtractive model.

@Guy-dv9xw 4 жыл бұрын

Say you have a white piece of paper, the paper reflects all colour so it is white. If you add red paint then the paint absorbs (removes) all other colours EXEPT red which is reflected. Hope this helps

this reminds me of that dress phenomenon that people were arguing about few months back. so with that dress example, when you combine 2 colors, do people perceive it differently?

@silkwesir1444 5 жыл бұрын

yes, it is related to this, but a little more complicated. when you are taking photos, there is something called white balance. to put it simply, it's a feature that is supposed to correct the colors in the picture according to the light, like explained in the video with the street lamp example. Our brain does this too, and in the case of the picture with the dress, there are very few hints about the lighting situation in that picture, so the brain basically has to guess what it is, and for some people it guesses one way, for others it guesses the other way.

Is it true that the primary subtractive colours are CMY or Blue, Yellow, Red? Why are they different?

@simperingham 3 жыл бұрын

You can construct any colour system you want in art, but the one that is most useful to us is RGB or CMY (notice that they are just opposites of the same thing). If you mix all three CMY paints (or inks, dyes, playdohs) together you get black, or at least a dark *neutral* grey. If you mix R, Y, B, you get a brown-ish colour. Neither is “wrong”, but one is much more useful.

so in this concept, mixing blue paint (doesn't allow green and red) with yellow paint (doesn't allow blue) would result in black. While in real life it actually makes green.

Because when you mix colours what you do is changing the quality of the surface. then these principles of light do not apply there.

madness. the primaries are secondary and the secondaries are primary. my brain hurts.

@indigosunset70 5 жыл бұрын

easiest way to understand this, is this way. sun emits green, orange, purple, which are the real primary colors. and you, the painter, cant emit light, you can only play with pigments and you notice you cannot create yellow, blue, and red by mixing two colors together. you can only create the true primary colors of green, orange and purple by mixing the secondary colors of yellow blue and red which you mistakingly call primary or more important, only because you cant create them. as for white and black, dont ask. shhhhhhhhhhhh

Wow this info is completely wrong. Red, yellow, and blue are primary colors. Green, orange, and purple are secondary colors. Magenta is a combo of red and purple. Cyan is a combo of blue and green. White is subtractive and you'll know when you add white color to any color, it gets lighter. Black is additive. As you've shown, you can extract red from purple by adding yellow (a color with a spectrum closest to white). Your info is wrong
