LiveCycle Designer ES4 - Changing non focus textfield content fill colour

Originally posted this question in the wrong forum.... Hopefully have better luck here...

Is there a way to change the fill colour of the content area of textfields when they do do not have focus?

The following changes the fill colour of BOTH the prompt and content areas of a textfield, which is more than I need..

TextField1.border.fill.color.value = "0,255,0";

The following changes the fill colour of the content area for a textfield when it has focus, which I wanted anyhow.

TextField1.ui.oneOfChild.border.fill.color.value = "0,200,0";

I want to be able to change the fill colour of the content area for a field (or all fields, if possible) when it DOES NOT have focus!

Thanks
