::The last band is tolerance, and there can be as many bands before that as the manufacturer needs. It's always the last band, no matter how many come before.

:There's two "standard" versions of colour banding that I know of, the 4-band and 5-band "precision" resistors. Some resistors may also have a red band after the tolerance band to indicate that it's "flame-proof" – or at least very high temperature resistant. The 4-band system indicates first digit, second digit, multiplier, tolerance like people have said so far. In the 5-band system the bands indicate first digit, second digit, third digit, multiplier, and tolerance. Bah, in verifying my facts I've found a 6 band system (really? Give it up already. :P) which is: first digit, second digit, third digit, multiplier, tolerance, temperature coefficient (in ppm/ºC or ppm/ºK relative change). Heck, why don't we code the power dissipation on to the resistors while we're at it? Instead of colours let's switch to a micro-bar code or QR code. (Sorry, slightly OT.)
