8% of the male population has some form of colorblindness (for women it’s around 0.5%). I have deuteranomaly colorblindness. If you search for images on the internet related to that type of colorblindness you’ll find representations of how we see color and how we see the world.

It is not a fun condition to have, and leads to lots of problems in my everyday life. This blog post accidentally accentuated that issue, since the colors are (to what I can understand) very similar looking to me as a colorblind person.

1 in 12 men and 1 in 200 women go through the same sorts of experiences, and it’s worth it, if you aren’t color deficient, to try out some of the colorblindness sites and see the world as we do.

Get more than one, someone with red-green and blue-yellow color blindness are going to have completely different experiences

Pro-tip: there are browser extensions able to simulate various kinds of color blindness.

That is better then a random friend, because a.) there are various kinds of colorblindness b.) you wont ask the random friend to work for your company for free.

For sure, but if you don't have any friends, don't discount the value of using tools such as CoBlis:

.. to get an idea of the impact of your UI design on color-limited folks out there ..

I used this a few times to great effect, it was very revealing to see that my carefully selected teals and ambers were incomprehensible to some folks I really wanted to use my apps .. didn't take much iteration to come to a happy palette though, just needed a bit of care.
