Resistor that is Red Red Gold Gold Silver

[mattbatt]

I'm not a newb but this one has me and google stumped.
What is the value of a resistor that's colors are Red Red Gold Gold Silver? what does the extra silver or gold stripe mean?
No I'm not color blind and the resistor calculators say it can't be done or doesn't exist.
It's resistor R7918 on board Delta Power supply board "runtka798wjqz"
It measures 2.2 ohms on board

Red red gold gold is 5% 2.2ohm. It's possibly to indicate reliability.

The first four bands are the usual IEC: red red gold gold = 2 2 x0.1 ±5% gives 2R2 ±5%.

The fifth band is open season, unfortunately (resistor) manufacturer specific.

Note your resistor is mounted on standoffs, pink body and the low value make it a current-sense resistor.
These have a safety aspect as this part likes to burn up spectacularly if a switching transistor shorts.

It would be a flame-proof fusible resistor. But I am not sure who made it, i.e. Yageo, KOA, Welwyn, TT, Futaba etc.

Fifth band:

White: fusible
Gold: miniature fusible (usually with pink body)
Yellow: "constant voltage fusibility"
Black: sometimes wirewound fusible resistor, but I see film types too
Violet: Vishay NFR25H

Some series use coloured fifth band to denote fusibility overload rating (4x,8x,64x).

The internet is a wondrous place where even the most niche question can be answered.
Thank you very much That resistor appears to be still good but the color code confused me.

Thank you very much Mr Redwire.
