CFP: Joseph Alber

I think I may have studied Alber before, because the experiments are familiar, but I've must have forgotten his name. Anyways, the reading assignment and the interactive websites illustrate how the relationships of various colors can alter other colors in how they are perceived. I found all of the website examples fascinating, but especially the Color Mixture in paper. In the example, there are two sheets of paper that overlap in between them and shows of colors can influence our spatial perception. The color shift of the middle can determine the transparency of the two sheets and their whether the left sheet appears above or below the other.

In the reverse grounds experiment, there are two blocks of colors with an "x" in the middle of them that are the same color. Changing the background color of the blocks can alter how the middle "x" appears. For instance, if I change the background to yellow in the left box and purple in the right, the "x" in the yellow box appears purple while the "x" in the purple background appears yellow.

The last web example somewhat similar to the reverse grounds experiment, but focuses on how context can influence our perception of color. I changed the inner hue to the same color and the inner hue of the left side appears darker and brighter on the darker background than the lighter background.
