Different colors in dropdownBoxes.

Hi

I am having dropdown boxes in my table.

There are 5 columns in my table and thus 5 dropdowns.

These dropdowns can contain 3 possible values among which 1 would be pre selected.

Now, based on this selected value i have to change color of dropdowns.

i.e. dropdown with value1 will be in color1

dropdown with value2 will be in color2

dropdown with value3 will be in color3

Please guide me on how can i achieve this effect.

Thanks........
