Well, there is, but I'm having a hard time replicating the colors in the
Bozo has red, green, blue ---- and white.
I'm assuming this is the result of the usual Red + Green + Blue = <1, 1, 1> =
But when I layer textures, how does that all work - because the top texture's
pigment occludes anything under it, unless I use filter and / or transmit.
Which led me WAY back to this 1998 post by Nathan Kopp:
Very interesting and illuminating.
But I'm not sure what values of filter and transmit to use in order to get a
blending of colors to create white. I'm getting the sense that I can't use PURE
red green and blue with filter, but maybe I'm wrong?
Can someone with a far better grasp of rgbft addition / multiplication lend a
hand with a mixing equation?
I'm almost there....
