Great article. Ummm... dumb question, but... stars are colored? (Color blind poster here).

Yup.

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...

I usually ignore syntax highlighting. I can't see it well because it's tiny, and because the "designers" usually chose colors that are tough to distinguish, and sometimes very difficult to see at all.

For instance, the default console colors in Ubuntu are TERRIBLE (maybe for everyone). The output of 'ls' uses blue letters on a black background for some type of file, and I literally cannot see those. Ditto for some errors in Emacs (e.g., trying to exit w/o saving a file). That output is invisible.

If you are an engineer and decide to do something with color in your UI, please get some designer help and listen.

I am not color blind and I've never noticed star colors. They just look white or yellow to me. It must be very subtle.

Is it obvious to everyone else? Do colored dots stand out in the sky? Or is it a subtle thing?

I watched a youtube video where a color blind guy in his 50s was given a pair of EnChroma glasses for color blindness, put them on, and had a strong emotional reaction, like a deaf person hearing for the first time.

Then I read the wikipedia article (https://en.wikipedia.org/wiki/EnChroma) that says "they do not restore normal color vision, and claims in excess of this by the manufacturer have been characterized as marketing hype ... They are simply a very expensive pair of hunting glasses ... How could they possibly work? The answer is that they can't."

I liked the video and now my feed has dozens of similar ones with similar strong reactions. If they don't work why the reactions? Am I missing the videos where they just say "meh"? Is it a placebo effect or maybe they're just playing it up for the gift givers? I guess the test is whether they continue to wear the glasses for long.

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 red or green color (or amber/yellow, they are equally hard to distinguish for people like me from green).

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…

Could you share the app name? It would make my life a bit easier (I hate those red/amber/green leds that look identical) :)

On iOS, it's "Color Blind Pal".
