On the ones I have the colours are evenly spaced, the bulge at each end has a colour band and then three in the middle all equi spaced making it quite confusing, all five are equally spaced, with no obvious one nearer an end.
As you say, it can be quite confusing - particularly with 2% (red) and 1% (brown) resistors - I must admit, I've taken to measuring them before fitting recently, using my Bangood component tester
Some times the last band is thicker. or maybe the first bank. lol
If you get a 5% resistor table, or 1% resistor table, you will see standard values.
Example for 5% is 4700 ohms. There should not be a 5% 4600 ohm resistor.
If all the resistors came from the same place then you find one that is right then you should know about all of them. Very likely the "tolerance" band will be the same on all. Black for 1%. Maybe you are lucky and all have a last band of black.
It would have made a lot of sense to have the tolerance band twice as wide as the others, or the space between the tolerance and the others twice as wide, but hey the standards committee must know best and didn't think it was necessary.

Couldn't agree more, I use my DMM to check the R values. The blue metal film R's are the worst for determining the colours, especially red, orange, brown, as they more or less look the same.
