This is peculiar but I’m sure there’s a good explanation (which I’m not qualified to supply). While working on the new painting shown in the last post, I was disoriented by a magical changing-pastel trick. One pastel stick+two color backgrounds=two effects. The pastel in question is a mauve. When it goes on the turquoise background, it appears to be dusty-rose pink. Put it on over the salmony-pink background and it shifts to blue.
Perhaps it’s some sort of brain-retinal-thingy going on. If it’s an illusion, it sure had me reaching for the cooking sherry. But then again, even the camera sees it.
Any color experts out there? I vaguely remember something from art-school days that covered this, but, dang!
I do love surprises. This sort of qualifies.
