/** BGR 3:2:3

 *
175
 * Even though we try 3:2:3 color scheme here, an 8-bit framebuffer
176
 * will most likely use a color palette. The color appearance
177
 * will be pretty random and depend on the default installed
178
 * palette. This could be fixed by supporting custom palette
179
 * and setting it to simulate the 8-bit truecolor.
4055 trochtova 180
 *
181
 * Currently we set the palette on the ia32, amd64 and sparc64 port.
182
 *
183
 * Note that the byte is being inverted by this function. The reason is
184
 * that we would like to use a color palette where the white color code
185
 * is 0 and the black color code is 255, as some machines (Sun Blade 1500)
186
 * use these codes for black and white and prevent to set codes
187
 * 0 and 255 to other colors.
