TComboBox und TDBLookupComboBox Selection Color

[madref]

Mein Deutsch is nicht so gut. Derhalbe stelle ich meine frage im Englisch:

TComboBox or TDBLookupComboBox have a selection color.
Is it possible to change that color?
I also asked it http://forum.lazarus.freepascal.org/ind ... ic=32104.0. But nobody knows the answer there. Maybe here?
