Depending on how many different things you want to compare, it might be worth looking into 'IF' and 'Else'.
None the less here is something that i found from the internet (After a few seconds) which might help get you started.
Code:
compareResult = strcomp(string1, string2, False, CultureInfo.InvariantCulture)
Above is how to compare the strings...
And this site is how to change the colours of parts of a string...

I'm sure someone here can help you combine them if you get stuck.
Good Luck
