9.1 MΩ resistor colour code (9M1)
E24 series
9.1 MΩ reads as White · Brown · Green in bands. With ±5% it may sit anywhere from 8645000 Ω to 9555000 Ω.
Five bands
The first two bands are digits; the third is how many zeros follow. The gold band at the end is the ±5% tolerance.

Which end to start from · The tolerance band sits a little apart from the rest. Start from the crowded end. If you can see gold or silver, that band is the last one.
Same decade
The same twenty-four values repeat with a different number of zeros — 47 Ω, 470 Ω and 4.7 kΩ all start with the same two colours.

How to read this
- Colours are digits: black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, grey 8, white 9.
- The third band counts the zeros. Yellow, violet, red means 47 with two zeros — 4.7 kΩ.
- A five-band resistor reads three digits, so its multiplier band drops by one step.
- The tolerance band sits slightly apart, which is how you know which end is the back.
