Good news: the same finish paint finish works for interior AND exterior doors. If you thought a satin finish was best, you are correct! Same people like a high gloss finish on doors for its wipe-ability, but you can achieve that with a satin door as well without the sheen. Dark colors can be a be especially garish in a high gloss, but everyone has their own preference on this matter.
As for the front door color, as long as it doesn’t clash with the color of your house, the sky is truly the limit. It is a great place to show your home’s personality with anything from a sunshine yellow to a bright turquoise.
Interior doors can also be bold, but tend to be either white or an off-white. Other common finishes are grey, black, or beige. Another option is actually staining the doors so the natural wood grain shines through, but then you also have to have a nice wood door.
Like anything with the home, preference is key. There are no rules, just previously established guidelines meant to be broken.
