Is there a way to allow the end user to change the font color in a text field?

I didn't know LiveCycle existed yesterday so I have been using the Google a bunch.

I am building a request form and was asked if there was a way to change the color of font within a text field. (EXAMPLE: Original content is black. Notes are red)

I have 2 thoughts on this, one is to type it out and highlight then click a button to turn it red. The other way I am more partial to. Have a radial button that when off, types black. When on, types red. What is the best way to do this or is it even possible?
