hmm i was thinking about this. one color...i started thinking about what color a lot of things could be and still be recognizable, so i chose pale green, like lemon grass, because the sky could still look like a sky even if it were pale green, and the sea of course, and grass and trees and flowers...human faces might look strange being pale green but better than blue i guess. this is the color:
Have you ever seen a little tree frog up close? Their eyes sometimes are golden - positively golden, like real gold and there will be a rim of gold around the eye and some on their throat. One time I found one that had golden spots on its back too! So that's my favorite color GOLD!
