I mean that Blend(SColorPaper, SColorMark, 220) has to be evaluated at some point. From developer perspective, the most logical point is when he calls Blend. It this was supposed to work without SkinChanged, we would need to do something like changing all colors stored in widgets to functions. I do not think that is a good idea...

Mirek

//header
struct SysColors
{
   Color paper;
   Color ink;
   Color mark;
   Color highlight;
   ...
   void RefreshColors();

   ...

   static SysColors scs;

private:
   SysColors(){ RefreshColors(); }
};
Color& SColorPaper = SysColors::scs.paper;
Color& SColorMark  = SysColors::scs.mark;
//cpp
SysColors SysColors::scs;

Then

Blend(SColorPaper, SColorMark, 220)

will be evaluated everytime with refreshed System Colors.
