What about mosaic tile? Lots of colors, styles, sizes, and finishes to choose from. You can also mix tiles or keep it simple and uniform - whatever you prefer! This fireplace was done in a single color of iridescent tiles, very sleek and modern! (other colors available!)

Hi again- I have been looking at Benjamin Moores colors and have chosen a few you might look at. My technique for color choices is to buy several large sheets of MDF from the hardware and several paint samples that I think will work. Grab a plain white sample pot as well and just play with colors; if what you thought looked good in the shop and doesn't look good in reality, just add a bit of the white to lighten it and use the darker tones to deepen. Once you've found the color you like paint it on one of the large MDF sheets and live with it for a day or two and see how it looks morning,night, south side of building,northside of building. If the color that you like is one that you've mixed yourself, just go back to the paintshop as I'm sure B Moore would have the right shade so you can match it. Do you know the color name of the roofing? Is it IRONSTONE or MONUMENT? I'd be tempted to use that same color for the windows. My personal trick for contrast and trims is to take the main color and ask paint shop to make it up in 1/4 strength even lighter if need be. Good luck and post pictures when it's finished.

Black roof, black window frames and muntins, cream siding, cream (the same tone as the brick siding) garage doors and high gloss black front door. No other color but cream and black. http://www.houzz.com/photos/3245164/Atherton-Residence-contemporary-exterior-san-francisco

There was a similar discussion last week, maybe you can get some ideas from it: https://www.houzz.com/discussions/help-for-exterior-cedar-siding-trim-color-dsvw-vd~661559
