yes but you also need the length of your streak displayed

Not really. The proportion correct is more informative.

"streak" as i am using it (as it is used in baseball) means "all correct, but for how long", so the proportion correct is always 100%. a "three game winning streak" means you won 100% of the last three games, and 0% of the one game before that.

Obligatory: what colour space?

Yes I know it's probably sRGB because that's ubiquitous on the web, but "RGB" technically is not a colour space.

Also interesting people talking about how they estimate the colours in their head - sRGB is not perceptually linear so if you're good at this game you've kinda reverse engineered the sRGB transform in your brain.

In the English language, they call it "red" In the programming language, we call it "f00" 4096 words for colors!

f00 is 3840

f00 is red, 1000h is the number of colors

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

I played a few rounds but it doesn't tell you what was correct, so there's no feedback to improve guesses.
