I'm making a superapp but I'm not a grafik designer so the visual side of things is giving me a headache

Can you help me design the front page? Here are a couple of color themes I've come up wit.
The right one is pretty crazy but according to Sherwin-Williams color theory the colors go together.

Give me working pallettes and other ideas on how to make this look like something the entire humanity will be using in a couple of years.
