finding and showing difference in 2 strings

if i have 2 strings lets say the following:

My favorite color is blue
My favorite color is red

how would i go about returning just the part that has changed, in this case "red"

i tried to do this using regex and whatnot but the position of whats changed isnt constant. that same text line could change later as such:

My favorite color is red
Your favorite color is red

in this case i would want to return "Your"

any modules or help would be sweet.
