How many colors are there?
Christopher Pagli, I agree with you 100%. Color does not exist in isolation, a door is an architectural feature that should be be styled and colored within the context of its setting.
It's not the color, and it's not the model number, it's how you manage the experience of the buyer entering the property. When I come up to a house with a poorly-designed entry, I have a certain feeling of what I'm going to find inside.
All the best,
