Agreed. The only text that should be yellow on white is the word 'Warning:' (And that should really be Black on yellow, or something like that)
And even then, maybe an orange or something would be better.
I like to reserve red for Error: myself.... Trying to read colored text is hard, so you may only want to make words you don't actualy have to read as colored. (Ie, warning and error as colored text bring attention to an area, but you can tell yellow = Bad, red = worse, so no need to actualy read warning/error)
Btw: Never used red on black for things you want people to read. some color blind can't see it. (they don't see red, so it appears black on black)
