I have always noticed, my favorite art is in Black and White. Colors usually muddle things up, and people never get colors right anyway. The only times I like when color are present is when one color or two colors are the center of attention. Like I said, people mess up colors normally.
Like in my drawing class--we are using soft pastels to draw... and I hate it, because we are not to use black. Everything looks effed up, because color is involved. I know that within life, color is everywhere, but seriously, does it need to be within art?
My two cents...
