Color Blindness

Color blindness or color vision deficiency is the inability or decreased ability to see color, or perceive color differences, under lighting conditions when color vision is not normally impaired. "Color blind" is a misleading term; there is no actual blindness but there is a fault in the development of either or both sets of retinal cones that perceive color in light and transmit that information to the optic nerve.

A problem of sorts with in the eyes that presents problems in seeing colors. Occurs in males more than females. Though they can be color blind. Color blindness is genetic, and can be found in generations following a color blind individual. You cannot identify color blindness on a computer, a real eye doctor/ doctor must be consulted.
Color blind people, normally do not like to be 'tested' by having to identify colors. Some people will ask about an obvious color (i.e; a person's skin color) and accuse the color blind individual of faking this sight deficiency.

Some people have also learned to some what force themselves to see a color by substituting it in their mind. For example, a colorblind person may see the grass as a reddish color, but think of a green color and merge it into their sight.

Just as color perception (and in turn blindness) exists on a spectrum, so too does the ability to experience emotions.

Most people who experience color deficiency, do not have issues with all color (red and green are most common). Color blindness can also come with heightened awareness in other areas...like better than average night vision or a keener sense of smell.

These details parallel well when describing people with emotional deficiencies, in that:

(1.) Someone on the spectrum for narcissistic traits, often still keenly feels rage, envy, hatred and fear.

(2.) Narcissists experience the above emotions more often and at greater intensity than the average person, BECAUSE they lack the ability to feel other emotions (like empathy) which might otherwise (ironically) diminish and balance those feelings out.

(3.) Even a full blown psychopath with no neurotypical fear response, (I.E. only feels an adrenaline rush) is not 100% emotionally colorblind. They still experience pleasure in a limited, ego driven sort of way. If this were not the case, they would have no motivation to do anything, (including anything bad.)

(4.) Total lack of emotional feeling and complete colorblindness, are both incredibly rare, and can signal something more serious...like a brain injury or a neurological condition.
