Not sure if I’m taking the bait but here goes.
Science is a set of processes where you take belief out of the equation. You can start with something akin, which when you have informed belief you have an hypothesis which you set out to prove. You don’t hold that as truth and anything not falsifiable is not a valid hypothesis.
Science is not a religion, it’s just a thing. Plenty of people need to belief to function and end up having (even a blind) faith in science, using it as a religion.
On your second point I’m with you on the last part though I think you are calling religions and believes things that are organized religion and religion.
Think of a base and look up what highlights or contrasts it. Red or Blue calls for black or white, or maybe brown to beige. Green when dull calls for browns. Orange calls for black more than white, some darker blues or jeans too. Purple and violet like green, or grey or beige. Pink goes better with white than black. If you want several look at how flowers combine the multiple colors (besides all the green). Those are the combinations that generally are enjoyable to see.
Edit: I just wear black or blue as a base and add red as highlight most of the time. Red shirt. Red belt, white and red shoes. And for whatever else I have specific outfits I don’t mix with anything else. Somethings I look like a metal head with band shirts and long hair. The next day you’ll see me wear basics and light jeans with a straw hat.
