I’m reasonably certain we’ve had this thread before, but can’t search.

I have access to these, but am color normal. CB people I know who have tried them thought they were sort of cool but not life-changing. No tears.

I’ve also used the ones they make that simulate colorblindness. Again pretty cool, but limited utility.

He was also astounded by orange:  
“Was ist daß?” [Orange] “Daß ist orange?!?”

Das, not daß.

**Mahaloth** - I found the [video with the guy reacting to skin tones](https://www.youtube.com/watch?v=uYz23OxgNpo). It’s not quite as dramatic as I remember, but still, it’s his big take-away.

I’m also dueteranomalous (sp?). I had a problem with a website (local Pizza online ordering) that the designer used a pale green background and pinkish click boxes. I could not see them at all. But I can see the cardinal hiding in the bush. It did cause problems in Chemistry lab, where an indicator changed from green to blue (or was it blue to green?) and I couldn’t see it change. It was supposed to change after titrating 30-40 ml of something-or-other, and after 125ml the instructor came over and asked about it.

I seem to recall reading somewhere that traffic lights are not quite what they seem: the red light has a bit of orange in it, and the green has some bluish. Although I do remember a certain 64 Impala that was a bluish green color. I could not see the bluish, and picked out some touch-up paint by eye. It looked fine to me when I used it, but everybody else saw a polka-dot car.

One thing I’ve wondered is how well they work with RGB screens. The red, green, and blue are fixed wavelengths, just combined at different intensities. Are they wide enough wavelengths the glasses can block out some and keep others clear?

Either way, could they make a screen that is designed for colorblind people, by using wavelengths that are more easily distinguished? Use the most saturated green that’s as far away from read as possible, for example.

That, plus red is on the top and green is on the bottom.

Excerpt in some places like in Florida where it’s horizontal.

Interestingly, in Canada, when the signals are horizontal, the lights are different shapes, round or square or diamond or triangular.

I would expect they could - _World of Warcraft_, for example, offers something like 8 or 10 different filters for people with various forms of colorblindness to make their game more accessible (I recall some definite issues with scrolling text across some backgrounds in the Barrens, Stranglethorn Vale, and Feralas in the old days). Generally, it doesn’t happen because either there’s a lack of perception that some folks could use that, or it isn’t seen as profitable.

Interesting, looks like it’s green circle, yellow diamond, red square, mainly in Quebec, New Brunswick, and PEI.

I also seem to recall seeing some in the Niagara region of Ontario. Glendale Ave at the rte 57 e-way. I think there are a couple around Halifax, N.S. But it’s been a while.
