From racial color blindness (wikipedia):
A color-blind racial ideology can be defined as holding the belief
that an individual's race or ethnicity should not influence how that
individual is treated in society. This is further divided into two
dimensions, color evasion and power evasion. Color evasion is the
belief that people should not be treated differently on the basis of
their color, while power evasion posits that systemic advantage based
on color should have no influence on what people can accomplish, and
accomplishments are instead based solely on one's own work
performance.
This sutta quote still covers it best, I feel:
“Don’t ask about birth, ask about conduct;
for any kindling can kindle a flame.
A steadfast sage, even though from a low class family,
is a thoroughbred checked by conscience.
SN 7.9
Any kindling, any piece of wood, can be used to kindle a flame.
Don't discriminate the type of wood or kindling.
Essentially color blindness.
