Moonlight is for the most part just reflected sunlight, so it's not surprising that the colors are very similar. Obviously it's much less bright, by a factor of 500k according to Wikipedia, but that's what this sensor is about.

You can get similarly startling images from a plain point and shoot camera by installing it on a tripod and taking long exposure shots of things. You need 30 to 60 seconds exposure, sometimes available as a "starry sky" scene mode. Architecture is particularly suited as it tends not to move around. :) Even a cheap, small, P&S sensor is much more sensitive to light when you expose for 60 seconds, all while being completely noise-free.
