Those are not RGB values. Instead, it's saying "Go get the system colour
for this instead."
You need to go check GetSysColor(). I strongly suspect that you'll find
that the clxxx values match the COLOR_xxx values with 0x80000000 added.
In other words:
if (colour & 0x80000000)
{
colour = GetSysColor(colour & 0x7FFFFFFF);
}
// now extract RGB value as previously
