I am red-green colorblind and for most of my life was stuck with the game “what color is that” and “what color does that look like.” These are games that non-colorblind people play in trying to understand color blindness. What they don’t understand is that colorblind people can’t do that. They can’t see the colors the same way and don’t have a common reference point for describing the colors. When I purchased this app 4-5 years ago I was caught in a problem of picking colors to paint my house. My friend would show me paint samples that looked, to me, exactly alike and ask me which I preferred. (To her they looked quite different.) When I would say they look exactly alike, she would get upset thinking I just wasn’t interested. Then I downloaded the app and tried it out by taking a picture of the paint samples and, from the “how colorblind people see it” asked her to pick which one she liked best. Her answer “they all look the same” followed by “oh wait, when you tell me they all look the same you mean that they all look the same.” The tension of the moment went away instantly. Since then, this story has repeated itself more times than I can imagine. Somebody would say “look at the colors of this” and I don’t get it. So I whip out my app and say “this is what I see” and they get it right away. “Oh, you can see that the leaves have changed colors, but you can’t see all the color variation. I get it.” Besides helping me relate to others, this app has a few useful features that I use whenever I’m in a quandary about color. The “helps colorblind people distinguish colors” feature lets me quickly see “oh, I bet I’m not understanding something others see here.” It also lets me quickly figure out which shirt is purple and which is simply blue. The color ID feature then lets me zero in on particular things and get a rough idea of the color other people will say something is. So I super highly recommend this app to anybody who’s colorblind and frustrated with color-sensitive people just not getting it.
