Question

Can you readily distinguish between the pigmentary colors yes or no

Answer 1

Color-blindness is the inability to distinguish the differences between certain colors. This condition results from an absence of color-sensitive pigment in the cone cells of the retina, the nerve layer at the back of the eye. (See "Look Inside the Eye.")

Most color vision problems are inherited and are present at birth. Approximately 1 out of 12 males and 1 out of 20 women are color blind.

Answer 2

Yes we can.

The wavelength is light which a pigment reflects back is what we see. For example, plants show green color because they contain chlorophyll which reflects green color.

Similarly, many photosynthetic organisms show different colors because of the different pigments they have which contains different compounds which reflects light of different colors.
