Turn label of a field red when data has changed in another field

I am attempting to change the color of a font in a label to RED if the value of an adjacent field has changed.  Doesn't matter what it changed to, I just need it to turn red if the item has changed at all.  I am new to this so any help appreciated.  Maximum points awarded.  I need it urgently!

Also need to know - when the "adjacent field" changes - how does it change?  Is the adjacent field a user input field or is it databound and read-only?
