Wiki on Color Blind Glasses
In addition to starting my MSc last month, I’ve also been spending some time cleaning up the terrible state of color vision articles on Wikipedia. Today I published a new article, which until now was just a few lines on the colorblindness article and in the EnChroma article. Color blind glasses (color correcting glasses) now…

A Cure for the Colorblind: Roadmap to Gene Therapy
FOOTNOTES #1 Heredity Because the gene therapy only targets the photoreceptors, and only affects cells in the retina (and possibly other areas of the eye), the genomes of the gametes (eggs and sperm) are unaffected. This means that the new copy of the gene is not inherited by the children of the individual who received…

First human cured of colorblindness!?
A paper was published at the end of August in the journal BRAIN that shows possibly that the first case of colorblindness has been cured. This comes after 13 years of apparent stagnation in gene therapy for CVD, ever since the Neitz Lab cured dichromacy in 2 squirrel monkeys in 2009. The study involves 4…

Can cops be colorblind?
TRANSCRIPT One thing we can probably agree on, is that police should be more colorblind… but while you may be thinking colorblind in the figurative sense – less racist cops – I mean colorblind… in the literal sense… because in the majority of police forces around the world, the colorblind are restricted from becoming police…

The Science Behind the Ishihara Test
Footnotes FOOTNOTE 1: CONE MOSAIC (5:07) The small changes in luminosity curve are often due to differences in the cone mosaic. The retina is made up of the four photoreceptors (3 cones and 1 rod), but these proportions change from person to person. Some people have more red cones and some more green cones, and…

My least favourite traffic sign
Another short up this week. There is a traffic sign that means “give way to oncoming traffic” often seen on single-lane bridges that in europe looks similar to the sign pictured below. Since protans perceive red as darker, in many conditions, this sign can appear all black and therefore potentially be confused with a sign…

How a made-up color blindness infiltrated the internet
Footnotes FOOTNOTE 1: ANOMYLIZE While this is not a real word, it is supposed to be derived from “-anomaly”. The proper spelling should therefore be ANOMALIZE, not ANOMYLIZE. Yes, it’s a petty thing to complain about, but it’s also indicative of the lazy naming that was happening in these simulations. It’s like they are trying…

New FAQ and Tools pages
Last week, I put together some new content for the website. I was introduced to Adobe’s new color accessibility tools and needed to highlight them somewhere, because they are an absolutely brilliant tool for facilitating colorblind-accessible design. So I made a Tools page, where I outline that and 3 other tools that I use all…

My favorite way to explain colorblindness
Last week I made a short for YouTube that I have been thinking about for awhile. The absolute quickest way to describe what is happening to colors for the colorblind… is just to squish a color wheel. Here for the reddit post with some discussion.

Indian Universities Open Up Slightly
The most common complaint among the color blind, is how many careers we are prohibited from having. In the west, it is common for the military, police and aviation to restrict entry to the red-green colorblind, but in the developing world, the prognosis for the colorblind is much bleaker. When I say the developing world…
