> The idea of taking a screenshot of the terminal and then parsing that to determine the true colour support is definitely novel,

A better way to do this is to send `OSC 1 0 ; ? ST` (query foreground color), `OSC 1 1 ; ? ST` (background color), then `OSC 4 ; {n} ; ? ST` where {n} is the nth XTerm color.

OMG really!? That link is blocked for me for some reason. If that OSC code is widely supported it's going to make things sooooo much easier.

It’s very widely supported from my experience. This is how asciinema captures terminal palette.

It’s supported by any xterm compatible terminal emulator. But like with most things in this domain, expect plenty of edge cases where it should work but doesn’t.
