rainbow series
n. Any of several series of technical manuals
distinguished by cover color. The original rainbow series was the
NCSC security manuals (see Orange Book, crayola books);
the term has also been commonly applied to the PostScript reference
set (see Red Book, Green Book, Blue Book, White Book).
Which books are meant by "`the' rainbow series"
unqualified is thus dependent on one's local technical culture.
