Reg: Background color for the ListGrid fields

Hi,

How can i give the custom background color for the ListGrid fields while editing.
We need the same for all types of listGrid fields like text,combo,select.

We are working on the below environment:

SmartClient version : Isomorphic SmartClient/SmartGWT Framework (9.1p_2014-09-04/PowerEdition Deployment 2014-09-04)

Browser : IE9

Thanks in advance
