I’m so confused. This is something people know? I mean, I can work it out from first principles knowing how color mixing works, but it sounds like people just … know them? I’ve been programming for almost 40 years and it would never have occurred to me to memorize this sort of thing.

I got 14/20 on my first try just by knowing how the color mixing works. A few simple rules:

- Higher values mean brighter colors

- The closer the individual colors are to each other, the closer to "gray" it looks

- R + G = Yellow, R + B = Fuchsia, G + B = Teal

First try: 16/20 https://imgur.com/a/c0yUOlw Excellent game!

Good job! That’s really good! Oh damn I didn’t realised it was you! Dear HN community, susam built the GuessMyRGB game which was a huge inspiration for this game. Please take the time to play it!! https://susam.net/myrgb.html

Here is another one my friend shared with me that's interesting. The time constraint adds some excitement! https://color.method.ac/

Thank you for sharing!

However, you both ask about colors and use color for confirmation. This unfortunately is both confusing and makes a not nice overlap of one modality used for two things.

Quick solution: just use the correct color. Use other modality (e.g. shape V/X or text "Correct!" vs "Wrong!")

I doubt anyone has many of them truly memorized. It's more like having the ability to quickly see each hex character and understand roughly what percentage that is, then quickly visualize the resulting color. My methodology playing this is to just convert each hex character to high, medium, or low, so you end up with something like "high red, medium blue, low green."

Couldn't get above 3 for numerous tries, after 5 minutes or so managed to get to 18! I learned a lot playing this (and reflected on things I already "knew" but never reflected on why). Thanks!

I tried about 5 times and never got more than 3 right. It would be better if they started out a little easier and then increased the difficulty. Currently it seems random. At any time you might get three nearly identical green boxes and it’s game over.

4096 colors is not too much to memorize.

I like it, but when you make your guess the mystery color should change to the color it describes, not to green or red. You should use some other aspect to indicate success - shape, motion, font, anything other than color. You already have it shaking for an incorrect guess, so that’s good.
