 * palette. This could be fixed by supporting custom palette

 *

 *
 * Note that the byte is being inverted by this function. The reason is
 * that we would like to use a color palette where the white color code
 * is 0 and the black color code is 255, as some machines (Sun Blade 1500)
 * use these codes for black and white and prevent to set codes
