MOROS operates in 80x25 VGA text mode and supports standard ANSI escape sequences for color manipulation.
There are 8 dark and 8 bright colors:
+--------+--------+--------+--------+--------+--------+--------+--------+
| Black | Maroon | Green | Olive | Navy | Purple | Teal | Silver |
| (30) | (31) | (32) | (33) | (34) | (35) | (36) | (37) |
+--------+--------+--------+--------+--------+--------+--------+--------+
| Gray | Red | Lime | Yellow | Blue | Fushia | Aqua | White |
| (90) | (91) | (92) | (93) | (94) | (95) | (96) | (97) |
+--------+--------+--------+--------+--------+--------+--------+--------+
The control sequence CSI n m can be used to print a text in color:
> print "\e[93mYellow\e[m"
Yellow
The background color can also be changed by adding 10 to the color code. It is possible to change both at the same time:
> print "\e[93;46mYellow on teal\e[m"
Yellow on teal
The values of the colors can be customized.
After its installation MOROS will run /ini/palettes/gruvbox-dark.sh at the
end of each boot to load a Gruvbox color palette by default.
It is possible to change this behavior by editing /ini/boot.sh.
