Combobox - Background Color

[BarkingDog]

Can anybody please tell me why it does not appear to be possible to change the background color of a combobox? Whatever I select from the Style tab seems to be ignored and the color defaults to a sickly yellow. I've even tried forcing the color through HTML to no avail

Hi, I may have this wrong, but is the box part of a form. It maybe picking up on a Google bar if you have one on your machine (Google auto fill).
