You can do it from the command line. Use Cntrl-V ESC to insert a literal
escape (echoed as ^{ ).
% echo '^{[3;30x' -> yellow foreground, blue background
% echo '^{[14;1r' -> set standout mode to yellow foreground,
blue background
The sequence: ESC [ 3 ; <number> x
means: set the PC color mode to <number>, where <number> will be used
in this way:
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| blink | background |bright | foreground |
| (fg) | color | (fg) | color |
Colors:
black 0 0 0 0 0 0 | 0, 0
blue 0 0 1 0 0 1 | 16, 1
green 0 1 0 0 1 0 | 32, 2
cyan 0 1 1 0 1 1 | 48, 3
red 1 0 0 1 0 0 | 64, 4
magenta 1 0 1 1 0 1 | 80, 5
brown 1 1 0 1 1 0 | 96, 6
white 1 1 1 1 1 1 | 112, 7
gray 1 0 0 0 | 8
light blue 1 0 0 1 | 9
light green 1 0 1 0 | 10
light cyan 1 0 1 1 | 11
ligth red 1 1 0 0 | 12
ligth magenta 1 1 0 1 | 13
yellow 1 1 1 0 | 14
bright white 1 1 1 1 | 15
So, for example, blinking yellow foreground on brown background is:
128 (blink) + 14 (yellow foreground) + 96 (brown backgroun) = 238
The standout mode works another way: Here, the foreground is given
first (as a number from 0-15) followed by background as another number
from 0-15. The same color combination would be:
fg = 14
bg = (128 + 96) >> 4 = 14
So you would use "ESC [ 14 ; 14 r".
OK, I hope this was understandable for everyone, it was mostly found
with hit-and-miss tactics :-)
