Annoyed by the super-saturated, sometimes-too-dark colours of the Linux console?
Here you go: `echo -en "\e]PxRRGGBB"`, with `x` being a palette index from 0 to F and RRGGBB an RGB hex triplet.
If you want to automate it without affecting non-tty terminal emulators, check `$TERM`, like so:
if [ "$TERM" = "linux" ]; then echo -en "\e]P0000000" #black echo -en "\e]P82B2B2B" #darkgrey echo -en "\e]P1D75F5F" #darkred echo -en "\e]P9E33636" #red echo -en "\e]P287AF5F" #darkgreen echo -en "\e]PA98E34D" #green echo -en "\e]P3D7AF87" #brown echo -en "\e]PBFFD75F" #yellow echo -en "\e]P48787AF" #darkblue echo -en "\e]PC7373C9" #blue echo -en "\e]P5BD53A5" #darkmagenta echo -en "\e]PDD633B2" #magenta echo -en "\e]P65FAFAF" #darkcyan echo -en "\e]PE44C9C9" #cyan echo -en "\e]P7E5E5E5" #lightgrey echo -en "\e]PFFFFFFF" #white # clear # uncomment this when the background is non-black to clean up the screen fi
(Naturally, those are just example colours that I stole from somewhere better than here.)
You can also use the setvtrgb command with a file containing three lines of 16 decimal values (0-255) each:
R, G, B, R, G, B, R, G, B, R, G, B, R, G, B, R G, B, R, G, B, R, G, B, R, G, B, R, G, B, R, G B, R, G, B, R, G, B, R, G, B, R, G, B, R, G, B
And yes, it line-breaks inside RGB triplets. Sigh!
Here’re the default values:
$ cat /sys/module/vt/parameters/default_{red,grn,blu} 0,170,0,170,0,170,0,170,85,255,85,255,85,255,85,255 0,0,170,85,0,0,170,170,85,85,255,255,85,85,255,255 0,0,0,0,170,170,170,170,85,85,85,85,255,255,255,255
You can stick that in your `/etc/profile.d` to have it run on startup.
Or, if you save the colour values used for `setvtrgb` as `/etc/vtrgb`, they should be applied automatically before you even log in. That one’s probably the most straightforward.
I don’t seem to be using any of those methods and still get the nicer, pastellier tty colours I want. If only I knew how I did that…
