Moonlight is typically white, and as such contains the full visible colour spectrum, similar to the sun. This is evident from such phenomena as Moonbows. The faintness of the light however makes color perception difficult. When given time to adjust, the human eye can usually detect stronger longer-wavelength colours, such as red or yellow. To quote Wikipedia.

"It is difficult for the human eye to discern colors in a moonbow because the light is usually too faint to excite the cone color receptors in human eyes. As a result, they often appear to be white. However, the colors in a moonbow do appear in long exposure photographs."
