After some experimenting, this appears to work properly (please let me
know if it doesn't; I'll add it to CVS if it does):

color brightblue "(\$|@|@@)?\<[A-Z]+[0-9A-Z_a-z]*"

My best guess as to why is that "\<" marks the beginning of a word, and
punctuation isn't treated as part of the word, so the "\<" has to be
after the punctuation.
