I can confirm that I see both an orange car and a 21. I’m not colourblind in the "I can’t see any colour " way and I can drive a car and see traffic lights without any problem but I do percieve colors differently enough to get in arguments with friends and family about the colour of stuff. I think it’s called deuteranomaly
Edit :the more I know!
Colourblind isn’t the complete absense of colour, e.g. everything looks black and white. With deuteranomaly, you are the actual textbook definition of colourblindness… There are different levels of it, but all can still perceive colour - it’s just whether the difference in colour of the spectrum is detected correctly.
Deuteranomaly (/ie) is the reduction in reactivity of the red-colour receptors. That means your perception of orange/red/brown is less than those with normal vision.
For those with normal vision, this is a great chart. But, if you’re colourblind, it’ll be more confusing for you, sorry!
If I were to guess, it might be because purple isn’t a wavelength of light, it’s like a glitch in how we perceive light with the two cones opposite to each other in the spectrum being stimulated at the same time without the middle one.
For any practical purposes in every day life, purple is a color, it just doesn’t exist outside our perception.
Can I just tell you how much I hate those Ishihara tests? I don’t see shit in that OP one (which was exactly what I expected).
Once upon a time, Panasonic did a print ad for one of their new color printers that was a dot test that read “Panasonic”, with nothing else on the page. Not super-effective advertising - although I suppose color-blind folks weren’t necessarily the target demographic…
Yes, they do.
I kinda hate them because non-colorblind people generally say one of a few things when conversations about them come up: “OMG do you really not see any numbers on there? It’s so OBVIOUS”, “Wow… so what color is this [insert random obvious thing]?”, or “So you’re colorblind? How do you deal with traffic lights? LOL”.
poor bastard :(
Ok, now I get it. It only works if you are american. That 7…
Okay I saw 21 but I am colorblind
I’m not color blind and never realized that these are made to show different numbers for those who are and are not. Never paid any attention to it, but now I can clearly see the 74 is made of two different colors/shades. Huh.
