She used a group of women who each had four cone cell types as her test subjects.The contrast between cyan and magenta is divine. The yellow glasses let cyan appear more green and the magenta glasses in contrast let cyan apear more blue. This creates the effect of a "true-cyan" (google that), a more true mixture of blue and green. Compared to "true-cyan" normal cyan seems almost white.

Tetrachromacy, just like Enchroma glasses, is fundamentally controversial. ~12% of women are carriers for R/G CVD, and they all have the first step to being a tetrachromat (having 4 cones), so its a good place to start, but having 4 cones is the easy part. It could be indirectly related to the autism.It is therefore impossible for an online test to investigate tetrachromacy. Do females see more colors?
