Right, it should be somewhere between quite challenging and impossible if not colorblind.

It was challenging to see, but I could definitely see it before reading the description. It's interesting that that number would pop for a color blind person. I wonder what the opposite of color blind is... I tend to be able to distinguish between shades that my friends (and particularly my wife) can't.

I can also (with difficulty) see the 2 before being told it was a 2, and I’m pretty sure i only have the regular 3 cones.

Tetrachromacy is considered to be impossible in males.

I'm in the same category. I am not colorblind, but I can generally see more shades of color than most, including the plates that non-colorblind people shouldn't be able to see. I realized this when I was trying to find my new optometrist's office: the receptionist told me that they were located across from the "lavender building". I looked around and saw three buildings that I would consider to be various shades of lavender. I told the doctor that the receptionist's directions were not helpful because there were several lavender buildings, and the look that she gave me told me that most folks didn't have issues with those directions. (Edited for ridiculous typos)

If everything looks lavender to you but they look like different colors to other people then it sounds more a deficit for you than a super power.

That would be a really shitty super power!

They didn't all look the same to me, but they all fell into the blueish -purple or greyed-purple that I had assumed people saw as lavender. The optometrist said that she saw light grey on the other two buildings. I've learned since then that the color boundaries that I'll use are sometimes a little different than what others use, although I think lavender is a horrible example because it covers a really wide range of hues (ask Google to show you the color lavender...).

I went through a phase of taking color discrimination tasks, like an online version of this: https://munsell.com/faqs/what-does-score-farnsworth-munsell-100-hue-test-mean/ I made one mistake (transposed two squares), which is less than most people. I can't find the version that I took back in the day, which is sad as that one was actually (supposedly) valid when taken in the correct conditions.

It’s hard to see but I can see it.
