Eep.
Well... this makes me think that I should've kept my tertiary color chart. Heh. *blush* I kinda hated color charts in that section of Visual design so they got smushed up and tossed around Christmas.
*goes off to look*
Quite honestly, it's like a gradient scale, black-white with colors in between.
But instead of black and white you use the primary/secondary colors. (to do the basic ones; ours had about... 12 different scales to make, so it was more then just the three otherwise).

Ok. So if you had that image on your screen. You'd take a ruler, find the middle point and from that point, place your ruler evenly across so that it ran through whatever center you found. Now then, you'd take the colors on either side of the rulers edge, and mix them together in various weights to either color (such as taking a whole bunch of purple and adding just a drop of yellow) until your color fades out completely to the yellow kinda thing...
*sighs*
If I could find a better picture, I would. But to be honest, I can't. *shrugs helplessly* did that make any sense at all? *goes back to looking for examples*
Oh come on now... I can't be the only fine arts student to have done this....

The bottom of this picture has some of the tertiary colors. Red-green kinda thing. (if done properly, they aren't brown!)
Evisceration is a sign of respect.
