Re: Early Morning Ponderings : The Nature of Colour
Phil, I really don't like your computer analogy. Negative afterimages do not involve any outside effects on the eye. They are caused by just looking at one colour for a short time. Second the changes caused by the background can be very dramatic, more than a change in shade. Our mind percieves colour based on a colour contrast mechanism. I have to study now, and I don't know the details off the top of my head, but I will bust out my textbook and get some more in depth explanations for this thread later tonight.
