+Most items in the =ef-themes= collection are designed to use colors from
+many sides of the spectrum.  Those items generally are inappropriate for
+people with red-green color deficiency or deuteranopia.  We do,
+nonetheless, provide a light and a dark theme that are optimized for
+such users.  The named of the themes are: ~ef-deuteranopia-dark~ and
+~ef-deuteranopia-light~ ([[#h:75d74aea-d17f-497f-a3b8-f0bf4c372de0][Loading a theme]]).
