Colour change on exposure to singlet oxygen?

Is there a dye that is particularly well suited to radical colour change on interaction with singlet oxygen, preferably non-toxic? 


Based on this answer: <https://chemistry.stackexchange.com/a/27633/41616> some compounds, such as tetraphenylcyclopentadienone, seem to lose their colour intensity, but what about changing / inducing colours completely, and what is the proper term for this process (chromism?) called?
