Can you imagine being color blind or do you know someone who is? If you aren't color blind then it's hard to imagine not being able to see certain colors.

There a thousands of people who are color blind. Usually, it's the reds and greens that people have a tough time seeing. Others just see different shades of gray.

EnChroma and Valspar Paint are trying to change that:

Nearly 300 million people experience the world without certain colors every day. ‘Color For the Colorblind’ is a short documentary about what happened when we partnered with EnChroma, maker of color blindness-correcting glasses, to help people experience colors for the first time.

The short film is moving and makes you realize you should never take color for granted.

You can find out more about these glasses and test your color vision online at EnChroma.com.  Just last week EnChroma unveiled their new Cx-65 Indoor/Computer Lens.

Here's more on Color Blindness from National Center for Biotechnology Information:

 Most of us share a common color vision sensory experience. Some people, however, have a color vision deficiency, which means their perception of colors is different from what most of us see. The most severe forms of these deficiencies are referred to as color blindness. People with color blindness aren't aware of differences among colors that are obvious to the rest of us. People who don't have the more severe types of color blindness may not even be aware of their condition unless they're tested in a clinic or laboratory.

Inherited color blindness is caused by abnormal photopigments. These color-detecting molecules are located in cone-shaped cells within the retina, called cone cells. In humans, several genes are needed for the body to make photopigments, and defects in these genes can lead to color blindness.

There are three main kinds of color blindness, based on photopigment defects in the three different kinds of cones that respond to blue, green, and red light. Red-green color blindness is the most common, followed by blue-green color blindness. A complete absence of color vision —total color blindness — is rare.
