This is off the top of my head, so it may not be exactly as the bottles say...this the jest of it:
BLUE: any application where vibration is a concern, it can be removed with ordinary hand tools
RED: same as above, but heat and special tools may be required to remove the parts once the red sets up
Green: I don't know who uses this stuff. We tried it once on a couple of bolts on a variable speed drive at work as they kept working loose. We had to DRILL OUT the old ones, retap for new ones when it came time to replace it...
If you get it on your fingers....don't touch your penis!!
(you shouldn't be touching yourself while working anyway...show some restraint...damn!)
