Light green SF and Fast green FCF are extremely similar triarylmethyl dyes that are almost the same color, and fast green can be substituted as a counterstain. Light green may have gone out of manufacture. Triarylmethyl dyes are potent carcinogens, and they could become hard to get or work with in the future.
