Hi, while doing an oil change at a friends workshop last night, I noticed the below leak. Is this likely an RMS? Somebody mentioned it looks like it could be coolant due to the colour? Any ideas?

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Where under the car is this? Can you give more perspective?

It looks like someone added some dye to track the leak. All I can say is the leak is at the seam of the engine / gearbox. There can be RMS, IMS, or gearbox leak.

That's a crazy color, even for coolant, so it may be dye as suggested. What color is the coolant in the expansion tank? However that's not a likely spot for a coolant leak, unless it's dripping down from somewhere very different (AOS or Oil Cooler are somewhat above there, but based only on my forum surfing, I don't think anyone has shown those to drip to the bell housing like that, but maybe?). It is the most likely spot for an IMS, RMS, (engine oil) or transmission issue (trans fluid). Surely the oil on your dipstick isn't bright green?
