This first video here talks about the different kinds of fuse you can find. There are probably a few that I don't have, but this should cover most of the colors and timing.
If you don't watch this video, the one thing to take away if anything, is that you should ALWAYS test your fuse to ensure it's the correct timing. I have had fuse in the past that burns too fast, or is completely mislabeled and burns 10 times slower.
