Style Packs

Is there such a thing as style packs anywhere? Have searched the internet but can’t find any.

I’m looking for pre-made styles as I have the design eye of a rock.

Hoping someone with an eye for design, colour schemes that go together etc etc has put some together as people have done for Filemaker.

I’m not sure if this is what you’re looking for, but I use coolers.co for sets of colors.
