25 "Face colors suitable for red/green color-blind users.
26 The color palette is from B. Wong, Nature Methods 8, 441 (2011).
27 It is intended to provide good variability while being easily
28 differentiated by individuals with protanopia or deuteranopia.
30 Basic, Font Lock, Isearch, Gnus, Message, Flyspell, and
31 Ansi-Color faces are included.")
