I use Color Blind Pal on Android. Been using it for a few years.

If you get it, I'd recommend going into the settings and increasing the sample size - it defaults to "small", which given the way it flickers I'd guess means "1 pixel" :) I use it on the "large" setting, and it works great.

Oh thank you, thank you.

I just installed that and do not know why I never tried to find something like this.

I am not sure how setting the kind of color blindness helps but having the color names displayed is wonderful.

On Android, there's "Color Blind Pal" that I use, doesn't use RGB values, but gives you names for the colors instead.

I’ve been happy using Cone on iOS after seeing it get brought up on HN previously. It’s paid, but it was worth it to me.

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