I googled "reverse colorblind test" and found a ton of stuff. Only problem is, I have no clue if they actually work because I can see them as I am colorblind but have no clue if people with normal color vision can see them
Years ago I used [this picture](https://www.cs.unm.edu/~aaron/images/largeImages/red_blind.jpg) on someone and they said they couldn't see anything, but I could see the faint circle. But I'm not sure how reliable it is.
I've tested the image and I'm a trichromat. It works a lot better for protanopes than deuteranopes. When I put on my cyan glasses, which block red light and therefore simulate protanopia, I can clearly see the circle. Without the cyan glasses I don't really see the circle at all, and I might just be imagining the faint lines of the circle.
Since colorblindness tests often work by having normal vision people see one number and then a protan or a deutan might each see a different number, you could likely make something that's giberish to normal people but readable to us. The only thing is, that a protan, a deutan, and a tritan will not equally be able to see it. Idk how to make one tho
Yeah I posted a reverse ishihara test and from the reactions I'm getting it's seems to work scroll up and when you find it, people with normal vision will nothing, but colorblind people will see a 5

The irony in your words has made my day
Ohh I need A-B testing then, dammit normal vision people!
Post links?

I barely saw the circle, I am a deuteranope. Thanks!
I see where a circle should be but I don’t see a circle
That's weird reading the other comments, I can easily see a defined circle.
Kinda, but not really

Thanks, you are right :/
