Hi there Lucy,
Looking long and carefully at your original post, I did manage to inwardly digest this...
And in the sample page I looked at, the entire DTD was also red
I would suggest that there is probably a fault in your dtd. :(
I use either...
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
...and they are both shown in a rather delicate shade of blue. ;)
