One more note actually -- could you keep the original colors here?

For walking and hiking I changed to the original colors.
I still kept cycling now being green instead of cyan, as I added swimming as blue think the old cyan is very close to the default one and 3 blueish colors are hard to distinguish.

I'm still open to changing it to original behavior if this is important to you, though 😉 .

Fair enough, no strong preference from me here. Feels like this should be customizable at some point anyway (not for this PR though)
