[neurosphere]

Hi! I wrote the Neurosphere article you're discussing, and noticed this lively comments section. I agree with the question you're asking - if she was born this way, why did she question it? From the research I did on her life, it appears that she always assumed people could see these colours, and apparently when teaching her students in art school she would try to say things like "Try to depict all the colours you see in this leaf, like the turquoise and orange on the sides..." and her students often just found it too embarassing to tell her they didn't see any of these colours. She slowly started realising that her colour perception may be different, until one day a neurology student taking her class suggested she took a genetic test. That's it. Since then I suppose she has really harnessed the results of the test to market her vibrant art as reflecting her 'tetrachromatic reality'. Some people have commented on Twitter questioning this, and it's something I think I will write about in the near future because it's a completely fair point.
