Quote - I always thought that moonlight should be at least silver-gray because the moon is gray, in other words the color of the light bouncing off it should be the same as the moon, plus a hint of blue (the AO of the night sky perhaps).

Gray means reflects equal amounts of all colors, maintaining the RGB proportions. So - yellow reflected on gray is just darker yellow.

If you shine blue light on a gray surface, it is the same blue just darker.

Shine red light on a gray surface, it is the same red, just darker.

So you said it wrong. The color of the light bouncing off it should be the same as hit it.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
