The theory of relativity in the color spectrum

It's still purple month over at so scrappy but I am working on my guild challenge piece.
It expresses a poem I wrote about my connection with trees... so I thought I'd discuss the
Theory of Relativity. It applies to artists using color, how one color relates to another, can change them, how the blending of three colors is so much more satisfying than using one. Right?

In the picture above, which is mother nature playing with her paintbrush, how many shades of purple are there? Or is it blue? Maybe pink?

how about this flox??
Lavender? Purple? Blue??

The first picture would probably be purple til you saw the next one, and is it purple or pink?

Whatever it is, it really stands out in the Spring against the brown and green ground cover.

That's a lesson for quilting and painting as well.

Many shades of purple here and note how they look against the gray rocks.
Also make note of the splash of fuchia in the foreground.
Adding a splash of unexpected color into artwork makes it more exciting doesn't it?

I took this picture for the comparison of blue and deep purple. The white and browns set it off as do the greens. How would you change the composition in your artwork? The color balance? Would you remove the white? The white gives you the third value, light light, the blue-purple is medium, the dark purple the dark dark.

These are violets. Are they violet colored? They are easily missed in a yard, and in fact the blossoms are very short lived but the leaves stay all summer like weeds. Violets sound very romantic but they are actually weed like most of the time. Is life all in how you look at it??
