But also it appears you missed that these changes aren't noticeable:
> Using a 12-bit colour depth limits the available colours, so slight changes to hue, chroma, and luminance must be made, but these are small enough not to be noticeable.
Again, I don't think it's about saving the disk/network the 3 characters. It's about minimalism and perhaps about developer experience: these colours are easier to read, write, and remember. Is that worth nothing?
Perhaps you use a CSS preprocessor and can define variables for your colours and don't need to write them down repeatedly. But perhaps other people don't. Or perhaps they're porting a colour scheme to many different applications. In these cases, three letter colour codes are superior to six letter ones.
