Curiously you picture is what I used to think. The primary colours in paint are red, yellow and blue. If you mix yellow and blue you get green. Then in a physics lesson I was told that the three primary colours with light are are red, green and blue. If you ADD red and green you get yellow. Not sure how a digital art painting programme would work if you mix red and green. Would you get yellow or brown?
The physics of color are completely different from artistic conventions and pigment mixing. For example, why would it make any sense to put purple "next to" red on the color wheel when they are on the furthest wavelengths of the range of our sight? Only because blue pigment and red pigment happen to produce purple. It's really confusing. Complimentary colors are the same: we just "happen" to think they look good together. Though it may be similar to music chords in the sense that their proportional wavelength difference might be similar . . .? It's really confusing, anyway. How do you get purple and orange in physics, by the way?
I think digital art programs are built to "act" the similar to paint, not actual light. A quick experiment on Gimp yeilded brown from red and green, though I had to lower the green's opacity more than red. (They most certainly did NOT make yellow. XDDD) When I tried yellow and blue they didn't really blend, just overpowered each other.
yes yes, that's perfectly true as well, but I'm being practical as in mixing paint, crayons, colored pencils ect...the basics lol computer color is cmyk (cyan, magenta, yellow, black) so im not sure about that lol
I've had this sitting in my inbox for awhile now, because I haven't had time to comment, but now I do!
This is VERY helpful, especially for people like me who have a tough time with colour theory (because I just plain forget about it when painting), and I thought there'd be more stuff like this in DeviantMentor (that's how I saw this; I'm in that group).
This is the first useful thing I've seen out of that group that fits with the idea of mentoring and learning. I joined that group to learn stuff like this, so your contribution is really something of a diamond in the rough for me. Thank you for adding this.
