color thory 2

This week I read the charter 13 of the book “Design Basic” which wrote by Davis A. Lauer. In charter 13, it’s basically talking about Color theory; the section call “Light and color perception” catch my mind, in this section, the author is talking about how does people only look at a color could know what subject it is. For example green color on the ground then it must be grass. In the book it said “our mind insists that the grass is green despite the visual evidence to the contrary” and in psychology it calls “color constancy”.
In the book there are also two pictures that show the color constancy, these two pictures are draw by Claude Monet, one call poplar on Epte, the other one call poplar. All subjects on those two pictures are the same, sky, trees and lake, the only different is the trees’ color. On the second picture “poplar”, all trees are yellow, also leaves are yellow. After we compare those two photos, we can notice that the season of the view is different. On the second photo, the season is autumn and the first one is on spring season. How could we bee so sure, because we know that during season all trees will become yellow. Now, here is the power of color.
