Trying make sense of this resistor colour coding.
I understand the principle and used to be able to read quite clearly, however these colours are difficult to ID.
These are on a strip marked as 1M.
But the colours as I see them don't add up?
Can anyone help this simpleton?

So how do I tell which is the tolerance indicator?
The tolerance band is suposed to be fatter. Mostly though, you can tell if reading the other way gives a weird value.
1M is a common value. 140R is not.

Thanks for that.
I read that the tolerance band is supposed to have a bigger gap from the last band. However, the tolerance band in that picture is about the same distance.
Sometimes the gap is larger, but this is inconsistent and can be quite difficult to distinguish for the 5-band resistors. The blue ones are also harder to read, perhaps because the colour contrast is not great.
If in doubt, I measure the resistance with a DMM.
