LSD and Color Blindness
by Erowid
v1.0 Dec 13, 2003
There are a handful of case reports of people with color blindness finding that LSD
altered their perception of color for the duration of the effects. Colorblindess is
not seeing without color, but a reduced ability to differentiate between certain
colors. It is not known how LSD changes perception of color or why it would alter
color blindess.
