Sorry about that, I usually remember to do it

I changed the script to use the 4 hex digits, and the black colors
still look weird

That’s the part I wanted to report as bug, all the colors that seem
to be specified as RGB but are only low blue values seem to be
handled differently (and, to me, unexpectedly) than most of the
other colors. It’s probably reproducible in a dark theme too, but
this is more visual with a light Emacs theme and a terminal
emulator theme that has a 0th palette colour that is light 
instead of dark

Yeah the other colors are okay, I agree
