In brief: Color blindness

Color blindness is the inability to see certain colors adequately.
This is an inherited condition (x-linked recessive) that affects men much more than women. The defect is in the retina and involves a problem with color sense in pigment granules. The commonest affect is trouble distinguishing red from green. See your doctor for an examination and proper treatment.

In brief: Color difficulty

This is (usually) an inherited inability to distinguish between certain colors.
The color receptors in the eye's film layer (retina) do not have the appropriate pigment, making it impossible to tell the difference between some colors, such ase blue vs. Green or re vs. Green. Color blind patients are not blind, and can use cues (position of lights in a stop light, etc.) to make up for this loss.
