I thought colorblindness tests were designed to be tricky and subtle, so I always passed them through very close inspection. I'm just colorblind.

I'm also colorblind and this cracked me up. I sent your comment to my friends who don't believe I can't see the numbers in those tests.

Had a friend who was absolutely convinced we were all pranking him when doing a colorblindness test. We were all doing the test because about 15 minutes prior, someone had asked him to grab a pink object off of a shelf and he came back with a green one in total seriousness

My mom had me tested in kindergarten when we were learning the colors and I couldn't get pink right. I kept confusing it with white.

My kindergarten teacher basically beat me with their voice for not being able to get my colors correct. Two years later during art class, I was sent to the school nurse to find out I was colorblind. However, they never told anyone, not even my parents.

It really should be a part of general screening upon admittance to primary school. Then again, this was 30 years ago, so maybe it is now.

In grade 6, an adult came in to class to do a colourblind test on everyone.

Projection screen was lowered, lights turned off, and a series of multi-coloured dots on many slides were displayed one after another on the screen.

In the dots, there were numbers / letters in colours different from the general background colour of the slide.

Adult: "Can everyone see the number?"

Almost everyone: "YESSSSSS."

One boy: "Ummm - there's no number on the screen!"

Pregnant pause.

One boy: "Oh yeah. Now I see it."

Almost everyone turns their head to look at that one boy.

Test continues.

Afterwards, the one boy was selected for further consultation...

What cracked me up is when tons of color blind people on Reddit discovered peanut butter is not green.

Have you tried using those colorblind glasses? Maybe something like Enchroma [0] or dichroic filters?

I can't speak for OP's colorblindness, but for me those do basically nothing.

I bought some for my son for his birthday. His response was "meh" so I returned them and he got some cash.

Yeah, they only help a specific subset of color blindness. But for the ones they do help it's significant.

I'm highly red/green colorblind. I got a pair of these as a gift and they allow me to differentiate between reds/greens much more clearly and to see red where I wouldn't notice without them. I know for some people they don't do much, but it makes hikes and such much more colorful for me!

Ooo! Good tip. Hiking with them.

This company has so shady marketing. They don't work as advertised.

The way they hire actors to play out wholesome videos and upload them to YouTube as if it's organic content, with massive fake users to comment and push up false claims and down vote brigade all negative comments should tell you all you need about this shady company.

Lol, yeah, sometimes an analytical mind works against you by taking things too seriously.

This is when it would've been good to ask someone about it.

I actually laughed at this one, you are a real hacker.

oh no

You should try a reverse colorblindness test like this: https://www.colorlitelens.com/color-blindness-test/secret-of...

That is one of the worst designed things I have ever seen. The instructions barely made sense at all for the first test, and for subsequent ones where you can enter 2 responses there is absolutely no indication what should be going on.

Wow, I was expecting this to be hyperbole but you’re right. No clue what you’re actually supposed to do on this site.

Yeah, I'm not sure what I did. But I went from question 1, to question 2, to question 2, then I saw a button saying "FINISH", so I clicked it and I got 12 answers wrong.

They're a site that sells goggles for the colorblind, so either way I wouldn't trust their colorblind diagnoses.

I just took a test. I cannot see shit in color. Haha. Fuk! Do those glasses actually help reverse this? I can clearly see RGB. But some hues look the same. Are people born color blind or is this wear and tear kind of situation?

Ignore this test. It doesn’t work on a computer. You need to take in in-person using specially-printed images.

Maybe they don't work to rule it out, but I am colourblind (as diagnosed in-person with specially-printed images by a professional optician) and when people have pointed me at these images on computers (only slightly less annoying than 'can you see this?', 'what colour is my shirt?') they've always 'worked' as expected.

This particular website doesn’t work on a computer. I’ve seen others that work well enough. This website is just broken. I believe this version is intended to only be legible if you’re colorblind, but good luck actually using it.

I’ve been in a lot of ophthalmologist’s offices for a variety of issues, and even had surgery as a child to correct one of them. The one issue I do not have is color blindness—and I’ve been given a lot of these tests.

This website doesn’t work on my iPhone’s screen. It’s impossible to discern most of the numbers, and the UI doesn’t instill confidence. Are they just using this garbage to hock their glasses to people who don’t need them?

This website is thoroughly broken, and nobody should even use it as a suggestion that they are or aren’t colorblind.

I think the numbers are visibles only if you have color blindness

That's right. maushu even said it's a reverse color blindness test. If you can't see any of the numbers, then you likely do not experience red-green color blindness.

It's a completely broken test. The "correct" answers at the end indicate two-digits numbers for "plates" when only a single-digit answer was possible.

I, without color-blindness, can't make out any numbers. A coworker who is red/green colorblind also could not make out any numbers. Then the results, as I said, show that the whole process was broken from the start.
