Isn't this just RGB, with 246 of the 256 values removed from each channel?

The site doesn't explain--what's the actual point of this? If we are seriously concerned about characters (which is generally silly in a gzipped CSS) why not just use 3-char hex like #a5c?

Mega Splash is the same format but with a unique curve annotation in the 4th digit. And i just made that up and its nelievsble because all encoding schemes are wonky and are extended on a per usecase basis.

I feel like I kind of get the spirit that this is done in, but it’s just not for me. Abstracting away from the existing 6 digit hex color codes just seems like extra work, even though it’s presented as ‘simplifying.’ It may just be too late for me - I’ve already learned how to express color sufficiently by mixing 256 levels of R, G, and B - it’s not useful to relearn how to abstract that to mixing 10 levels of the same, in a less exact less prescriptive manner.

I AM genuinely glad this person is having fun with the little world they’re creating, and that they’re bothering to share it.
