Explanation

Xanthophylls are yellow, orange, and red pigments belonging to the carotenoid family. They become visible when chlorophyll degrades (autumn leaf color). Chlorophyll is green. 'Leucophyll' is not a standard term - white pigments are typically chromoplasts without pigment. Erythrophyll is not standard botanical terminology.
