Day 30 #2

I had to squeeze in one more before the challenge is over.  This is number 6 in Tree Map, completing the red-violet section.  The final three, on the right, will be yellow-orange, making a triad color scheme. That means they are three colors equidistant on the color wheel.  Like red, yellow, and blue are.
I do recommend that artists keep a color wheel close at hand, and use it.
