Color RandomColor() {
	int num = Random();
	return Color(num&0xFF, (num&0xFF00)>>8, (num&0xFF0000)>>16);
}

Just some more comments Wink

Color RandomColor() {Color(Random(),0);}

BTW: Color BW() is useful sometimes, but it might deserve bit more readable name. What about ToGrayscale() ?

Honza

EDIT: Now I see conversion to grayscale is already available in Core:

int  Grayscale(const Color& c)
{
	return (77 * c.GetR() + 151 * c.GetG() + 28 * c.GetB()) >> 8;
}
