Use an image hosting service. Generally the colors at night are desaturated and, obviously, dark. Most people are afraid to go too dark, or overestimate how bright highlights are. The colors also tend to be cooler by moonlight than by sunlight.

Our eyes contains two types of photoreceptors for capturing light information; rods and cones..
The cones sense the red/green/blue wavelengths of light(the color), because there are 3 types of cones:

S-cones - sense short wavelengths (blue)
S-cones sense strongest near wavelengths of 420–440 nm

M-cones - sense medium wavelengths (green)
M-cones sense strongest near 534–545 nm,

L-cones - sense long wavelengths (red)
L-cones sense strongest near 564–580 nm,

Cones respond well when there is a lot of direct light, and they also provide more detail because they are located in the fovea of the eye(the part responsible for more detail). Rods are more sensitive to light and indirect light, but don't capture any color information. They are located outside of the fovea. When there isn't much light, the cones have difficulty sensing it, which makes your perception of color become less intense, also things become blurry because there is less direct light hitting the fovea. The rods pick up the slack in dim conditions because they are more sensitive to light, but because they are located outside of the fovea area, your center of vision is still a bit blurry, and your peripheral is blurry too because you don't focus in that area of the eye.

Also, here is a link that explains some more stuff, like why green may appear brighter than red during the night.. http://hyperphysics.phy-astr.gsu.edu/hbase/vision/rodcone.html
