You can change the color of the content in the control (and its appearance in the tableview) if you set its Text Format to RTF (Rich Text).

This will allow you to change the color and font style. Unfortunately, the background color cannot be changed.

For example, you can create a TextBox named cRich and programmatically (in VB) set its color with cRich.Value = "<font color=blue>BLUE</font>".

If the project is simple, you can set the value in the Property Sheet/Data: Text Format = Rich Text; Control Source: ="<font color=red>RED</font>".
