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...
Anecdotal, but I have mild color-blindness and love syntax highlighting.

Do you reckon AR glasses fix this issue?
Not sure why you're getting downvoted. This was my first thought. The posts above mention using an app to read RGB. An overlay using AR would bring immediate value, I would think. My colorblindness is mild. Can tell most colors but fail the petri dish color test around round 3-4, nothing pops out at me.
Can you imagine telling someone a wheelchair, that should just buy a portable crane to get into buildings that uses stairs?
I do also find that it’s quite hard to match up two similar colours in the red/green spectrum, regardless of size, unless they are actually next to each other. I also struggle to differentiate between bright green and yellow, dark green and brown and sometimes blue and purple; to the point where I don’t know which of the two to call something. This I guess is not related to edge detection.
As an aside, I love this kind of content - well written, interesting and not on some bland platform like Facebook or Medium. It reminds me of the sort of stuff I used to discover with Stumbleupon. Any recommendations where to find this kind of stuff, except for on here?

I'm also Red-green colourblind, and also use a mobile app to check RGB values of things! I also use a Windows traybar app that I wrote with Delphi about 15 years ago, which gives me a dropper I can use anywhere in the screen to see RGB values. I've also noticed that it's much more difficult to differentiate tones and colours of small objects. Cues were mentioned in the article, and I think I subconsciously rely on th…
May I ask what apps are both of you using?
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…

It's all white for me... Am I missing colors?

I think the point is devices should be designed to be usable by colourblind people, without having to buy an additional device. Can you imagine telling someone a wheelchair, that should just buy a portable crane to get into buildings that uses stairs?
And there are situations outside of product usability it will be helpful to know what is commonly seen. For example, when someone asks you to pick up X item at a store that is a color that you have a hard time identifying.

Just to clarify (for my own edification) If you look at the colors #FF0000 (red) and #00FF00 (green) does one look greyish or do they both look like the same color? Also, apparently this is news to many r/g color-challenged people: peanut butter doesn't look green to every one else. It looks brown (which I don't know if a separate color to you)
I am red/green colorblind. I actually knew about this because they tested for it the first time I got glasses, and it came up there. But for years afterward I never really thought about it; I’d be able to tell basically every color and only falter on some that seemed ambiguous to me but others had an easier time distinguishing–but I never ascribed this to colorblindness; I just thought it was I who didn’t know the co…

I can tell you that it's not about knowing my colors, the colors of the apples you linked look as different as white vs black to me. And they would look just as distinct even if I didn't know my colors.
Because "keep them far apart" on the spectrum might not be helpful when taken litereally, here is a link to Lines of Confusion Diagrams im CIE 1932 color space.

> "Second, use other cues if possible. Color is complex, so if you can add another component to a line on a graph, such as a dashed versus dotted pattern, or even good labeling, that helps a lot."
I find this easier said than done. My issue with alternative cues is that they often introduce a form of unintentional order or hierarchy. For example: When I want to plot two different variables and I want to avoid that one of them appears more important than the other I can do this nicely with color.
Other line attributes are not so easy. A solid line will always seem more important than a dashed or grey line and a dashed line more important than dotted one. Trying to change the dash and dot pattern so that they have similar grey values makes them hard to distinguish. I find color is the easiest way to distinguish things without introducing unintentional order.
