Usually Frame3D is used with clBtnHighlight, clBtnShadow colors - to 
draw raised or lowered surface. The best match on most widgetset would 
be to use Canvas.Frame3D for that purpose - then surface will look more 
native.

But if you need paticular colors and the same as in delphi Frame3D look 
then just use the same algorithm as in delphi: Left, Top sides are drawn 
with TopColor, Right,Bottom with BottomColor.
