Standard Color Code

Color	Sig. Digit	Multiplier	Tolerance
Black	0	1	-
Brown	1	10	-
Red	2	100	-
Orange	3	1,000	-
Yellow	4	10,000	-
Green	5	100,000	-
Blue	6	1,000,000	-
Violet	7	10,000,000	-
Gray	8	-	-
White	9	-	-
Gold	-	-	+/- 5%
Silver	-	-	+/- 10%
No Color	-	-	+/- 20%

Values are usually obtained by reading the colors in a left to right manner.

sig digit & sig digit * multiplier @ tolerance

For example if a resistor had four band of brown, black, red, and gold; this would be read as 1 and 0 multiplied by 100 at +/- 5% of the rated value (10*100=1,000)-- a 5% 1K resistor.
