Well I went to my colored hair. Excellent foam, well washed scalp and hair, but it is very soft, not dry, not confuses hair, scalp as well does not dry. As for color retention anything precise to say I can not, maybe I lightens hair a few shades (from dark blond to blond), painted every 3 weeks, during which time grow roots, but if the hair is lightened, can not imagine how paint can be washed off, I there is no such principle.
