If beauty doesn't require God, why should morality? (Bite me Dr. Craig.)

"Cerebral achromatopsia is a type of color-blindness caused by damage to the cerebral cortex of the brain, rather than abnormalities in the cells of the eye's retina."
~ Wikipedia

Cortical colour blindness is caused by brain damage to the ventro-medial occipital and temporal lobes. A possible explanation is that the pathway responsible for transmitting information about wavelength and its subsequent elaboration as colour has been destroyed at the cortical level. However, several signs of chromatic processing persist in an achromatopsic subject who, despite his inability to tell colours apart, can still detect chromatic borders, perceive shape from colour, and discriminate the direction in which a striped pattern moves when the determination of direction requires the viewer to ‘know’ which stripes have a particular colour. Perhaps only the information about wavelength that leads to conscious awareness of colour has been destroyed.

Would it be useful to an organism to "know" the color of objects in its environment? Their shape? Their relative location?
