Titled “PseudoIsochromatic” inspired by Ishihara’s colorblindness tests and the colors that are affected by people who experience colorblindness.

"A term frequently used to describe color blind tests, like the Ishihara Color Vision Test is ”pseudoisochromatic plates .” This alludes to some of the colored dots in a pattern that at first seem to be the same in color ie: “isochromatic” with surrounding pattern. However, it is not (false-“pseudo”), as the difference exists for a person with normal color vision, and the “hidden” number is visible within the array of dots.
