I got the confetti at the end, what did I find out?
There were 2 I had to just start hitting squares until I got it right, and one of those I did notice the different one once I started tapping, I probably could have spotted it if I was more intentional. This seemed significantly easier than the standard Ishihara tests for me, which makes me question how well it works to judge color vision. I’m red/green color blind and the Ishihara test usually have me skipping a significant number, because I don’t see anything… to the point doctors bring out a basic red, yellow, green cards to make sure I can see traffic lights.
I breezed through this test, with the exception of maybe one or two squares.
I’m red/green colorblind but constantly doubt if I am. Every few years I ask an eye doctor if I’m colorblind. The last time I did this they only went through a few pages of the Ishihara test before closing it and saying, “Yep, you’re colorblind.” I’m also able to read reverse Ishihara tests which my non-colorblind friends can’t.
I don’t think I’ve ever called something red when it was green or vise versa when someone’s asked me to identify its color. Red and green look quite different to me! However, I cannot for the life of me spot my dog’s red frisbee in green grass, or pick out a red character among a bunch of green ones without looking at each character. These are both things people in my family with perfect color vision do just fine and without difficulty.

This is basically a textbook description of standard red green colorblindness. Whenever you find yourself doubting whether you actually are red/green colorblind, just go strawberry picking with friends.
Yep. Whenever I say I am colourblind, people show me a tree and ask "what color is it?". And I have to explain that I know what red/green is.
An example I give is red flowers in green grass: I may not see the flowers at all unless I go very close.
Another one is while climbing indoors: say there is a purple route next to a blue one. Some handles I will clearly classify as blue, some clearly as purple, and some in the middle I won't be able to classify. But non-colourblind people will clearly be able to classify them all.

I'm extremely bad at picking fruit in our garden. I'll go to pick the raspberries, strawberries, or peppers and only find a few. Then my wife will go out and find several times my haul from the same plants.
It does seem like they use darker/lighter shades instead of redder/greener/bluer at the same intensity but I don't have the means to check if that's true
