Yes, this is "as designed".
In GDI+ "special" VCL colors like clXXX cannot be used.
GDI+ only accepts "real" colors like clRed, clGreen, etc.
In Firemonkey this is not a problem because "special" colors in Firemonkey do not exist anymore. Firemonkey only has "real" ARGB colors.
The solution for VCL is to use the ColorToRGB function, which converts from "special" to "real":
Font.Color:=ColorToRGB(clwindowtext);
There is special code in VCL TChart to control this problem for panel Color background (ie: Chart1.Color), but it can't be done for all colors everywhere, everytime.

Created attachment 120 [details] clWindowsText clwindowtext doesn't seem to work from v2013.09. The project attached works fine with v2013.08 but not with v2013.09. This color works fine if I change to GDI.
