If rule for form

Hi,

I am new to this program and am desperately trying do create a simple form. In the form I would like the user to be able to select a color from a drop down list and then when the color has been selected from the list, i would like the corresponding text box's text to be that color. so to put simply when i want the user to be able to change the colour of the text within their section via a drop down menu.. is this possible? if so could someone give me some direction?

Thanks alot,

Neil
