Right, unless it's a 1% tolerance resistor, in which case it's got an extra colour stripe. The first 3 stripes are for the value, a fourth stripe is for the number of 10's in the multiplier, and the fifth (brown) stripe is for the tolerance.Thus, for a 120 kOhm 1% resistor, it would be:
Brown-Red-Black-Orange-Brown
Sometimes it's a bit tricky to tell which end is which in the 1% resistors.
Incidentally, Gold is 5% tolerance, Silver is 10% tolerance, and if there is no tolerance band it's 20%. Occasionally a yellow band will be found after the tolerance band on older, 'vintage' resistors; this indicates fire resistance. Otherwise you use the colours as given in the preceding post.
