NAME
setvtrgb - customize the console color map
SYNOPSIS
setvtrgb vga
setvtrgb FILE|-
DESCRIPTION
setvtrgb sets the console color map in all virtual terminals according to custom values
specified in a file or standard input. With the `vga' parameter, it can also be used to
restore the settings built into the kernel.
When invoked with a filename or `-', setvtrgb expects input as follows:
color0_r,color1_r,...,color15_r
color0_g,color1_g,...,color15_g
color0_b,color1_b,...,color15_b
where colorN_{r,g,b} is the red/green/blue portion of the respective color in decimal
notation in the 0..255 range. To pre-seed a file in the correct format, you can use
cat /sys/module/vt/parameters/default_{red,grn,blu}
The meanings of the color values are defined as follows:
+--------+--------+---------+
| Normal | Bright | Color |
+--------+--------+---------+
| 0 | 8 | Black |
| 1 | 9 | Red |
| 2 | 10 | Green |
| 3 | 11 | Yellow |
| 4 | 12 | Blue |
| 5 | 13 | Magenta |
| 6 | 14 | Cyan |
| 7 | 15 | White |
