TDBAdvGrid and Delphi Appearance

I have a project in which the global appearance is set to a custom style (for example "Auric").
I have many TDBAdvGrids (ver. and I'd like to get the same look of the standard TDBGrid.
The TDBAdvGrid.Look property is set to glCustom, in the procedure Form.Create() I set the colors and column fields are dinamically loaded from a configuration stored in DB. 
When this project is run seems that a lot of colors I set are ignored and the look is not the one I want.
How can I solve this problem?
I'm using Delphi XE2 and TMS Components pack

Thanks in advance for your help.
