Since you have a blue roof and front door, why not continue the blue them with a very light blue? I'd go with about 2 or 3 shades darker for the trim. My neighbors started repainting their house yesterday afternoon, and went with a robin egg blue which is where I got the idea for this. I'm amazed at how much better their house looks that color than the tan it's been for over 20 years.

While I love the white, I think that charcoal grey would be a great choice and would really pop against white window trim. Good luck!

I would go with a medium-light grey and leave the window trim white. It'll look really crisp and clean. Any colour of door would go with that colour. Alternatively a med-light Olive green might be nice.

My husband works in the stucco industry and doesn't recommend dark colours as they fade quickly and depending on how your stucco is installed you may have uneven fading (we see a lot of bad stucco jobs where the washer fasteners show up as dark spots as the colour fades. Polka-dot stucco :P)
