Oh, we've been having a love affair with this color lately. We like to think of it as the grown-up version of teal; it's a little bit more staid, but still super-saturated blue with a hint of green. And we are crazy about this combination, as seen on a house in lower Pac Heights...
The gray really grounds the look, allowing the blue to pop without looking out of place alongside the more traditionally-painted houses nearby. We love how modern this color combination is, yet it is not jarring by any means.
And here's an example of how the colors translate indoors. The black accents add a moody vibe that we like.
