This piece is about color theory. The top left shows colors sorted by the brightness of their greyscale value. The top right is an example of simulated transparency. Actual semi-transparency could be made, but this is an approximation from the actual thing. The bottom right shows a difference in brightness. Finally, the bottom right has two squares with “inverted” colors. Inverting colors changes the hue, saturation, and value all to the opposite values.
