Engine Internals Discoloration

As my adventures in Mini repair continue, I pulled off the oil pan to replace the gasket and check for chunks of timing guide. Check, chunks present, timing parts ordered. As I’m looking up underneath the car I am wondering if...

1) Is this discoloration normal? and...
2) Yes or no, should I try to clean it up someh

ow while in here?

I’ve done and learned a lot on this car, but I’m not sure I’m ready to dive into pistons and valves and rings and such. At 78k miles, should I be trying to do anything in here? Pic for reference attached.

Looks similar to the color in my motor when I had the valve cover off to replace the gasket at 80k. I don't know much about engines honestly, but I think the color means it's maybe been pushed a little far on oil change intervals, but could just be normal. as long as you're not seeing sludge, I don't think I'd worry about it, but hopefully someone with more knowledge and experience will weigh in.

Looks pretty normal, as long as you dont see sludge build up. Or anything caked on.
