void vga_setpalette(int index, int r, int g, int b);
Note that setting color 0 will modify the background color and that setting any color in range 0 .. 15 will affect the operation of vga_setegacolor(3).
If the VGA_CLUT8 feature is set for the current mode with vga_ext_set(3) the r, g, and b values are in the range 0 - 255.
The vgatest(6) demo shows the basic use of this function.

This manual page was edited by Michael Weller <email@example.com>. The exact source of the referenced function as well as of the original documentation is unknown.
It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>.
Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
