... need your help in choosing my exterior doors.
Ah, it's not interior design, but exterior design.
I should say it is a Strange Question (is it serious?), but quite obvious for a (web)designer:
- Just as with a website, the right color of an element depends on the color of the rest of the elements, and on personal taste.
- We don't know the colors of the rest of the house, nor the environment of the house, nor your personal taste; so it's impossible to give an advise about the dark or light variant.
- Take a photograph of the front of your house, and paste in Photoshop or something the light colored door, and in another copy the dark one.
Compare, and make your choice!
