Who is claiming she is insane? She has the gene for it, the question is is she actually seeing these colors.<p>Seems easy to test. You can test if I see reds, for example, even if you are color blind. Example: here&#x27;s a rose petal that she says has many colors but we see one. Have her draw it and label it (not paint it, as not everyone can paint). Now give that same petal to another person that claims this power. Have them draw and label it. If their color maps agree, they are sensing something. If not, well, it requires more study. Seems pretty basic unless I am missing something.
