The color didn't come out so well in these digital pictures (I'll try to put better quality shots up soon), but the house is a sober grayish-purple (we tried to match Glidden's "Silver Night" but used Sherwin-Williams' new Duration paint which is supposed to last as long as I will own the house), the door a deep eggplant purple (we used Glidden's "Plum Escape"), and for the trim, I had the painters mix a tiny amount of purple in to pure white to dull the white a bit. (You can click on any of these pictures for a larger version.)
First, here is what my house used to look like (spring 1999).
