I've always wanted to ask this question. Do we have to rest our eyes
frequently to keep this phenomenon from happening? By way of example, if we stare at a red spot on a piece of white paper and look away, the
compliment/opposite color appears in our field of vision. Does this still happen to us when we paint? Is this phenomenon affecting our color and value choices if we stare too long at our reference photo or still life? I'm guessing it is still happening but not as noticeably as in the white paper test. Is "Fresh Eyes" something we need to do more often? Should we be staring less? Blinking more?
