Bezold Effect

Described in Chapter 2, the Bezold Effect is used to describe how a color may appear to be either brighter or darker depending on the colors that are near it. I think that this effect is really interesting because it changes the way that you perceive how the color looks. 

An example of the Bezold Effect is this design found on http://artistrendezvous.cansonstudio.com/web/guest/displayimage/-/display_image/1566563/kp1606/bezold-effect

The yellow appears brighter when it has a blue backdrop, compared to when it you see the yellow is in front of the more subdued yellow. 

Another example of the Bezold Effect is this picture of how cyan appears next to white, compared to how it appears brighter when next to the black color.
