Is there an equivalent "color index" for "system color" in VBA?

e.g. I'm thinking to color cells the same as a default button face color
(i.e. system color &H8000000F&) without having to create a shape or button,
but it doesn't seem to be possible from this very useful link I found in this
forum sometime ago...Is this right?
