These specific constants map to system colors, so the user can change
them in the display settings dialog if themes are not enabled. You
should not try to modify these colors at compile-time, that makes no
sense. And they are not yours to change at run-time either, since any
such change does not only affect your application but all of them. See
SetSysColors in the MS platform SDK docs.

Hi,
Bit related question, does anyone how to convert a color like clWindow color
to it's RGB values? I have some components that only accept RGB values but I
want them to match the form color for instance at application startup.

Hi,
Found it!
ColorToRGB accepts both 'normal' and 'system' colors and returns RGB values.
