This entry begins with the adjective a)ndrei/kelos (here in the masculine accusative singular or neuter nominative/accusative singular; either way, evidently quoted from somewhere) before turning to the neuter noun a)ndrei/kelon, a flesh-coloured pigment. For references to both usages see LSJ s.v. See also mu 1033.
[1] Adler prints the transmitted noun, krisis, but both Photius s.v. and general sense show that it should be krasis, "blend".
