Just wanted to add the point, also previously made on the list, that
there are actually a great many more Loctite grades than there are
For instance, RC/609 Stud and Bearing mount is also green, while 271
(which is a lower temperature, faster grabbing high strength formula
than 272) is also red.
Moral : you can't tell the Loctite without a part number.

> Blue - Loctite 242 - "low temp applications. Medium strength."
> Green - Loctite 290 - "wicking grade" - assemble parts, put on a "dab" and it
> won't come apart...marvelous stuff."
