Probs dont need but..
Tmux Wiki colors stuff
Debugging

Check Terminal:
echo $TERM
Check if TERM supports 256 colors: (Outputs Integer)
tput colors
Check flags set for TERM:
infocmp -x TERM_GOES_HERE
Use the truecolors.sh script below to test!!

I fixed the issue using the first article. But the tput colors command returned 0.
The terminfo just didnt have all the correct flags set.
However the output of the script clearly showed it working! 😄

  
## truecolor.sh
#!/usr/bin/env bash
#
# Use this script to test if you have true color support in your terminal.
# Usage: ./truecolor.sh
# If the color ramp is perfectly smooth, true color is supported.
