@khamer @JoshMerlino what is the 4:3 supposed to do in the middle of that escape sequence, before the 38 and 48 "extended" colour codes?
@mintty @wendajiang @JoshMerlino - please note that this gist is no longer maintained. Please add your comments to the standardterm repo instead.
@XVilka - this is why I suggested that the entire content of this gist should be deleted except for the link to the repo. It would also help to mark all the comments as "hidden".
After my confirmation. Xshell6/7 support truecolor. But you must set "Tools-Options..-Advanced" check the "Use true color*"
@coolmian would you mind please adding your notes as an issue on the standardterm repo ? (Preferably create a PR with a fix.)
Reminder to future readers who want to make a comment but didn't notice the warning at the top of this page.
It's now a full-blown git repo so please write your comments there, or clone the repo and suggest changes via a Pull Request:
git clone git+ssh://github.com/termstandard/colors truecolor

@kurahaupo yes, should have made this a long time ago. Now it's done.

OK, I've done it now
Just repeating this so that it's visible at the bottom of this conversation; please don't reply - the whole point is that this should be the last comment, to make it plainly visible when someone is about to hit "reply".
