I Can't Imagine Life Without Color

Maybe you've heard the word color blindness. Color blindness is the desreased ability to see color or differences in color. I am grateful, I can see color or differences in color.

I have a friend who is color blindness. I think it is a funny thing, until I find out what it is color blindness. For people with color blindness turns out it is a sad thing, because they can not see the beauty of the colorful world.
Color blindness have three types of inherited or congnital color vision deficiencies :

-        Monochromacy, also known as "total color blindness", is the lack of ability to distinguish colors (and thus the person views everything as if it were on a black and white television); caused by cone defect or absence. Monochromacy occurs when two or all three of the cone pigments are missing and color and lightness vision is reduced to one dimension.

-        Dichromacy is a moderately severe color vision defect in which one of the three basic color mechanisms is absent or not functioning.

-        Anomalous trichromacy is a common type of inherited color vision deficiency, occurring when one of the three cone pigments is altered in its spectral sensitivity.

Therefore I can not imagine my life without color. Will the same happiness as we can see all the colors?
