How well does this work for colorblind people?
- renewiltord 3y agoHere's a gradient for the kinds of colorblindness https://www.allaboutvision.com/conditions/color-blindness/types-of-color-blindness/ https://www.allaboutvision.com/conditions/color-blindness/ty... You can look at the gradient and answer your question. If you're curious how to answer it in future, I googled "types of colorblindness gradient" and clicked the "Images" tab. There were quite a few examples and you can browse to multiple sources if you don't trust one.

- sschueller 3y agoHow does a color blind person know if it's green or red at a traffic light? They can still see shades of gray and position.
- meepmorp 3y agoTraffic lights have a specific design and orientation which makes it easier to identify which light is on. Plus, they're up on poles or other places around the road. By comparison, the picture in the linked story shows lights that are more or less in the same location as other lights on a car. If you have a difficult time distinguishing color and you look at them while driving or walking, it seems plausible that they'd be harder to distinguish. I realize there's different types and severity of color blindness, but using color alone (or primarily) seems like not the greatest usability choice. I did consider these things when commenting.
