Yeah, I have a book that shows four, five, and six band resistors. On the
five band resistors, the extra band is for reliability by the following
chart:

Color Reliability (Failure % in 1000 hours)
--------------------------------------------------
Brown 1%
Red 0.1%
Orange 0.01%
Yellow 0.001%

Six band resistors, however, are entirely different. Bands 1,2, and 3 code
for *three* digits of the resistance (like precision metal film
resistors...I think), the forth band is for the multiplier, fifth for
tolerance, and the last is for a temperature coefficient. Here are the
values for the sixth band:

Color Temp Coef.
-----------------------
Brown 100 ppm
Red 50 ppm
Orange 15 ppm
Yellow 25 ppm
(no idea why the value goes back up again, that's just what a couple books
that I have say)

And here is a little to add to the last person's post about the tolerance
band. In addition to silver and gold, other colors have designated tolerance
values:

Color Tolerance %
-----------------------
Silver 10%
Gold 5%
Brown 1%
Red 2% (so much for consistency)
Green 0.5%
Blue 0.25%
Purple 0.1%

Well, all the info is rather superfluous but someone may find it interesting
or useful.

Five bands? I've never heard of those....
