Trim paint should look good with your wall paint and your floors. What color walls will you have? Are you likely to change the color scheme every two or three years or more like ten years from now?

A couple easy test runs for the black door idea: You can paint a large foamcore board with the black trim paint, then prop it up on the inside of your front door. Or tape a large black trash bag over the door.

I need to see your house and IMO all windows on the exterior should be the same what you do inside is all windows you can see together should be the same , bedrooms can be quite diddernt than the resyt of the house inside . As for the front door we need context .
