Hello!
You have few ways for doing that.
1. Set SkinData.CustomColor property to True and you can change color of the control by changing of the standard “Color” property.
Color of parent you can receive using the GetControlColor function which declared in the sVCLUtils.pas unit.
2. Change the SkinData.SkinSection property of control to “PANEL_LOW” of “GROUPBOX”.
Looking of the control will be changed automatically then.
Write me if I can help more.
