Emacs with 24 bits color in terminal

Troubleshooting

Recompile terminfo

Once the colors just stopped working, recompiling terminfo (see tic) worked for me. Perhaps there was an system wide update of terminfo and the format was changed somehow, so the old compiled files in my homedir didn't work anymore.

Terminals

Putty

Under settings->window->colours 'allow 24 bit colors'

environment variables

TERM=xterm-24bits
TERMINFO=$HOME/.terminfo/
COLORTERM=truecolor  # idk if this does anything.

tic

~/.terminfo/xterm-24bit.src

# Use colon separators.
xterm-24bit|xterm with 24-bit direct color mode,

compile
