Puzzle #3: The visual world of a tritanope
Which 3 of the colors shown above would appear the same to a tritanope?
Why?
Answer: green, cyan and blue would be hard to distinguish for a
tritanope because all three wavelengths fall in the same category. To a
tritanope all wavelength below 570nm look roughly blue. Any other
selection of three
colors from the five above would cross the category boundary and would
be easier to distinguish.
