Pics of the front of your house would be helpful. The other elements are important, i.e.: siding, trim color, etc.

Very dark purple.

If you google Van Deusen Blue door, there are several images. Very pretty color!

Thanks for the responses! Old Blue Jeans was a great choice. Our house is gray with white trim, so pretty flexible as anything will go with that. We just don't want the blue to be too dark or it will look funny with the black shutters. It should clearly be blue. I'm going to give Van Deusen Blue a try and see how it goes!

Also try Van Courtland Blue.
