Adding Color to a Color Blind World

I find the moving triangle illustration really confusing. It looks like the wavelength of the green sensing cones is somehow displaced spectrally in color blind persons.

My understanding of red-green color blindness (that can be treated by these lenses) is that it is caused by reduction of the response of the red cones (protanomaly) or green cones (deuteranomaly).

The proper relative response of the red and green cones is corrected by a specially constructed filter which restores the correct ratio. Because the red and green cone spectral response (L and M) is overlapping and closely spaced, this requires a precise optical filter.

I guess that's why you or I don't work for EnChroma

I had a psych professor in college who was colorblind -- all of his pants were a sort of dark grayish-greenish-blue and all his shirts were light blue, green, or white. So his clothes never clashed. Interestingly his colorblindness is what led him to study the psychology, more specifically, the psychology of perception. Gestalt theory was his major area concentration (so of course they had him teaching statistics -- which he did really well). He was an example of making lemonade when life gave you lemons.

Life tried giving me lemons once. I took those lemons and froze them then used them to break all the windows out of life's house at 2 AM.

Now life's a lot more cautious about what it gives me.

(Especially after that 'giving me a Banana' incident.)

Not too sure what "bones" have got to do with red and green colours

"EnChroma lenses separate the overlapping red and green bones cones"

Color blindness is caused by an abnormality in the X chromosome that causes the retina to develop bones instead of cones.

Here's a website with an app that helps colorblind people determine what colors are used on computer screens.

It's helps them figure out which line is which, on graphs that have colored lines, and so forth.

'What Color?'

Here is another free program for color blind folks:

Visolve is the software that transforms colors of the computer display into the discriminable colors for various people including people with color vision deficiency, commonly called color blindness. In addition to distinguishing colors and finding a specific color, it aims to help people with color blindness:

• to guess a normal color, and
• to feel the color gradations in natural scenery etc. by their visual information.

Visolve can execute the following three types of color transformation, filtering, and hatching:

1. Red-Green transform -- transforms redder colors to brighter, and greener colors to darker,
2. Blue-Yellow transform -- transforms bluer colors to brighter, and yellower colors to darker,
3. Saturation increase -- increases the saturation of all colors,
4. Filtering -- darkens all colors other than the specified color, and
5. Hatching -- draws different hatch patterns depending on color.

I would think you could use it with a cell phone camera to "correct" the colors in realtime...
