I didn't know he was color blind. I can't help but connect this to his famous disdain for syntax highlighting and colored text: https://groups.google.com/g/golang-nuts/c/hJHCAaiL0so/m/kG3B...

As a color blind engineer, I love syntax highlighting, but mostly for the "pop" and "fade" contrast effects rather than associating specific colors with semantic values.

I'm red-green colourblind (quite badly), and also use syntax highlighting for the same reasons - it highlights semantically different parts of the syntax (or not, as wanted) even though I have no idea what the colours actually are.

I have also red-green color blindness and it makes me really mad that a lot (like 90%) devices have a tiny LED that indicates if it is charged and the LED changes color from red to green when it is fully charged - I have to ask my kid or wife what color it is. Please please, if you work in hardware, make it a red/blue or green/blue colors for empty/fully charged, or make it blink, anything, just not tiny 1 pixel size…

Turn off light when charged, works for Panasonic batteries charger.

I'm r/g colorblind, and suddenly the indistinguishability of small colored objects makes sense now. Wow. Okay then. I hate multicolor LEDs with a passion. Those little amber or green dots look identical to me, even when you put them side by side. I use a phone app that uses the camera and shows me RGB values at a reticule. I've gone through rack and racks of equipment with that app, looking for things like dead drive…

> I can drive a car and I stop when the light is red and go when the light is green. I'm also slightly colorblind and pure green light would be harder to distinguish from distance (not critical because there is also light position, but still). That's why traffic lights usually have cyan tint.

I see traffic lights as red, yellow, white. At night from a distance this can be a problem.

I use Color Blind Pal on Android. Been using it for a few years. If you get it, I'd recommend going into the settings and increasing the sample size - it defaults to "small", which given the way it flickers I'd guess means "1 pixel" :) I use it on the "large" setting, and it works great.

Oh thank you, thank you.

I just installed that and do not know why I never tried to find something like this.

I am not sure how setting the kind of color blindness helps but having the color names displayed is wonderful.

-At a former employer, I volunteered - as in, bullied my way into - the test group for our SCADA GUI front-ends.

This resulted in palettes for both deuteranopes and tritanopes; our support staff on occasion had calls from customers who had inadvertently activated one of the color schemes for the chromatographically challenged - they typically went along the lines of 'Did you nincompoops have some colorblind sod do your GUIs?'

-'Matter of fact, we did. Would you like me to put you through to him?'

Is there a more precisely evocative term? color-disability, color indistinguishment. Color vision-impaired? Vision/visual-color impaired. Impaired color perception.

The word "blind" implies, at a first impression, nothing to be done for a visual use-case.

This is such a detailed description of the issues caused by red/green color blindness. I've had some issues in the past specifically related to small red and green boxes. When you do some operations work you'll eventually run into a chart like this [0] and, during an outage, you'll undoubtedly not be able to notice a scattering of small red boxes in this type of visualization. Similar with line charts. Telling the di…

I am colorblind. Just to be sure, there are no non-green boxes in the chart you linked to, right?

Colour (vision) deficiency.

Being tritanope, my favourite euphemism is 'chromatographically challenged'.
