| 释义 |
ˈcolour-blind, a.
Unable to see certain colours; unable to discriminate between individual colours, or shades of colour.
(The strict meaning ought to be ‘blind to colour’ as a whole; but as this rarely exists (except in the case of the totally blind), the term is applied with much laxity to any constitutional inability to discriminate between colours, the common type being inability to distinguish the red and the green rays of the spectrum from each other.)
