I'm r/g colorblind, the biggest takeaway from this article is that, there are different colors in the stars??

Re: Color blindness
#122One friend once told me that he would see 100% red down to 70% red as the same thing.
So after certain point, the intensity of red didn't matter.
Summer studies show that colorblind person don't get fooled by camuflage.
Anedoctaly, another friend got a LCD tv with a red dot in the middle of the screen. He sold the tv to the first friend because he had no problem with that dot...

#123I'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…
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)
Re: Color blindness
#124I'm red-green colorblind but the only way it noticeably affects my life these days is with the icons on Github's notifications page. A merged PR an an open PR have different shapes and the merged PR is blue and the open PR is green --- very easy to distinguish. But an open PR and a closed PR have identical shapes and are only distinguished by the open PR being green and the closed PR being red. Or so I'm told anyway,…
Made an issue based on your comment. Is this accurate? http://github.com/github/view_component/issues/495
I didn't know you could do that! Thanks!

I was flashing a router which seemed broken. Each flashing was failing. Then my brother came by and asked me if I was trying to trigger a failed flash? WTF? As you now guessed I was seeing these little motherfucker LEDs as red when they were green. I hate them with passion. And I work in IT, they are everywhere. I sent a few days ago a picture of my home fibre converter to my wife when she was out with friends so tha…
Do you reckon AR glasses fix this issue?
Ideally, colorblind people wouldn't have to deal with solely color LEDs as a signal in the first place.
I'd like to not spend money on assistive devices if I don't have to.
Re: Color blindness
#126Nice article. Small correction, humans are not old world monkeys (or any kind of monkey). We are apes.
Interesting, so English language has two words for them. e.g. in Polish both are "małpa" (and usually translated to monkey), similar to turtle and tortoise, for us it is a single world "żółw" (and usually translated to turtle).
It's partly an issue of language, but "old world monkey" and "ape" correspond to specific scientific classifications as well.

Not the OP, but I'm also R/G color blind and I don't believe I'd have any issues with those extreme versions of R and G. My issues happen with lighter shades.
For instance, 00AA00 and 00BB00 are very hard for me. 00CC00 is about when I start feeling confident I could recognize it as green, but it's be harder if the surface area was fairly small (for example text). On the red side, the recognition issues also extend to about CC0000.

That's a big reason for the order of lights in traffic lights. New lights, around here, are also getting reflective frames, so that people can better understand the position of the active light. https://pxhere.com/en/photo/265717
R/G colorblind here. I didn't realize how much I relied on traffic light order until I visited Houston, TX where the lights were horizontal. It was a very alarming experience.
Re: Color blindness
#129I've got mild red-green colorblindness (less severe than the author's); this article is great, and goes into much more detail than I knew beforehand. If I could add some suggestions to the author's at the end: * First, if you have the option of using one or the other, do so. Like, you can use red, blue, yellow, purple, and black for lines on a graph before you even need to find an additional color like green. * Secon…
> First, if you have the option of using one or the other, do so. Like, you can use red, blue, yellow, purple, and black for lines on a graph before you even need to find an additional color like green.
I don't see this advice getting much uptake.
First, green isn't a second thought for people with normal vision. It's a first thought. I can understand how this wouldn't be true if, to you, it didn't exist.
Second, the color space without green is harder to draw contrasts in than the color space with green.
Third, a friend of mine with red/green colorblindness always complained that he couldn't tell the difference between blue ("rare") and purple ("epic") items in World of Warcraft. (WoW has since solved this problem by throwing out the concept of item quality entirely, but the colors are still there anyway.)
So you're advising that people should make a quite unnatural choice, which will markedly reduce usability for almost everyone, but which won't actually solve the problem for the colorblind. It's just not a move that makes sense.

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 have the same issue, and use "Color Swatch" on iOS for this.
