What color to paint front door?

Yellow or blue

Royal Blue

How about a pale/baby blue

A pale yellow would look quite pretty

How about Annie Sloan Duck Egg Blue? It is a vintage blue/green.

Perhaps one of these door colors is what you have in mind?

Teal or some version of ocean blue would be beautiful.

Our neighbor had brown wood siding and rock. They painted their front door a dark purple. I loved it! But I guess they didn't because a few weeks later it and the trim on roof and side gates were a dark blue. That looked great too.

I would find large flower pots in a teal or aqua and paint the door to match them. Place the pots so that they make a nice 3-point composition with the door.

Think I am going with a light blue or teal, thanks for all the help

Here's something you might want to try before purchasing the paint:
