Usually the color bands are printed closer to 1 end of the resistor than the other. This is the band you start with.
First 2 bands are just digits (integers), 3rd band is the multiplier, then there is usually a tolerance band Silver=10%, gold=5%.
So these are 1 type of color codes, but precision resistors have 5 bands. The first 3 bands are integers, 4th is a multiplier and 5th is the tolerance brown=1%, red=2%.
