Here is a picture I took in May 2011, at Monkey Town (Western Cape, South Africa). And below is the sketch I drew of this picture 🙂

Color Matters

Because I can’t leave you without adding some knowledge.

We take color for-granted, how often do you stop and look up at the blue sky? How grey would the world be without color? Even with the loss of one color the world is a different place. Below you will see how the color blind view color.

Color blindness is the inability or decreased ability to see color, or perceive color differences, under normal lighting conditions.

Protanopia is a severe type of color vision deficiency caused by the complete absence of red retinal photoreceptors. It is a form of dichromatism in which red appears black and therefore human can see light only from 400 nm to 650 nm. It is hereditary, sex-linked, and present in 1% of males.

Deuteranopia is a color vision deficiency in which the green retinal photoreceptors are absent, moderately affecting red–green hue discrimination. It is a form of dichromatism in which there are only two cone pigments present. It is likewise hereditary and sex-linked.
