I'd recommend for every developer to get one or more colourblind friends. I have some, and regularly send them screenshots of what I'm working on to get feedback what they can see and what they can read/can't read. They've been absolutely invaluable for making sure their kind of people can't use my apps properly.

  It's obviously a typo (or an excellently delivered joke) but I did get a chuckle out of the idea of someone going out of their way to ask color blind friends for feedback just to do the opposite out of spite for some reason.

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. https://www.colourblindawareness.org/colour-blindness/colour-blindness-experience-it/ https://www.colourblindawareness.org/colour-blindness/colour...

    Some people lack in vision, some lack in reading and some lack in stopping themselves to reply to comments misunderstanding others.

        gortok lack in vision. You lack in reading. And I lack in stopping myself to reply to comments misunderstanding others. I love that I had to explain this :)

        Nope. The greater point here being we definitely benefit when we all understand one another better. Surely that point was not lost, yes?

  Most color blind men are mildly color blind, plenty even go through their lives without noticing. Yours is on the much stronger side of the things.

    A cousin of mine found out in his late 20's that he is red-green color blind.

For sure, but if you don't have any friends, don't discount the value of using tools such as CoBlis: https://www.color-blindness.com/coblis-color-blindness-simulator/ https://www.color-blindness.com/coblis-color-blindness-simul... .. 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.

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.

  On the other hand, the random friend generally has a great deal of experience with what interventions help and don't help. A filter shader generally won't tell you that substituting white for green in a red/green indicator is a great option, or that a colour that they can “see” is still ambiguous when you have to describe it: “I'm clicking the purple button, but it's not doing anything” “Purple? There's no purple in the app!”

> I'd recommend for every developer to get one or more colourblind friends. In the absence of any naturally occuring colour-blind friends, do you have any tips about surrptitious damaging someone's eyes to create one? :-) Though there are simulation tools avaliable which do a reasonable job, I'll probably stick to those where I have a concern. That feels less drastic.

  There's apps that can simulate color blindness, which can be used for testing purposes. This is such an app for iOS / macOS: https://michelf.ca/projects/sim-daltonism/ https://michelf.ca/projects/sim-daltonism/

Ubisoft release some tools to simulate colorblindness. It's easy to extract de color transformation from their shader directly. I'm not colorblind but I use that quite often to check roughly if the color palette I choose is fine https://github.com/ubisoft/Chroma https://github.com/ubisoft/Chroma
