Well, that depends on what you mean by "color code".
You can just set a control's Fore, Bac or Border Color
properties to make it always appear in the specified color.
If you want a control to be in different colors depending on
its value, then you might be able to use Conditional
Formatting (Format menu). In general, the most versatile
approach is to use VBA code in the control's section Format
event procedure.
