There is this book called The Old Moon and the New by Valdemar Axel Firsoff (Sidgwick & Jackson, London, 1969). In this book, Firsoff ask'd the question if our eyes are much more color-sensitive during bright daylight/sunlit circumstances, because during dark nocturnal circumstances our eyes "lose" the ability to see vivid colors. When we look through the telescope at the bright Full Moon, we want to observe through an additional dark grey filter, to avoid the blinding brightness of the moon's powerful retro-reflection from its sunlit regolith layer (what I call Dry Heiligenschein). This optical effect ("Dry Heiligenschein") is also called Shadow Hiding. Now, what would happen if we don't look through a dark grey filter and let our observing eye receive 100 % of the Full Moon's bright (retro-reflected) light, while the (white painted) interior of the telescope's dome is illuminated by very powerful white artificial lightsources, to create daylight/sunlit circumstances? Thus: first we let both of our eyes "adapt" to bright artificial daylight or "pseudo" sunlight. Let's say, half an hour in pseudo-sunlight and then... looking through the telescope at the bright Full Moon (sans filter of course). Perhaps... the subtle colors of the moon would become much more visible...
By the way, only a very small percentage of the world's population knows about the impossibility to see the Full Moon during the day. When the sun is shining through a dense (yet translucent) layer of Altostratus, most people think it's the Full Moon!
Also interesting to observe: the rare light-bluish / light-greenish coloration of the diffuse looking disc of the sun shining through Altostratus. I don't think there's an explanation for this optical effect.
The phase of the moon, such as the Full Moon, is a rather difficult subject to comprehend. When there's a partial lunar eclipse, most people think it's the Waxing or Waning Crescent Moon. When there's a Waxing or Waning Crescent Moon, most people think it's... (...or much more troublesome: many grown-up people still think it's a cut-out drawing of a banana shaped "smiling moon", hung up at the "ceiling" of the starry sky) (the Flemish "Janneke Maan" syndrome) (translated: "Little Johnny Moon").
But... wait a minute... there IS INDEED a possibility to see the Full Moon during, for example, noon. When there's a Total Solar Eclipse! The moon's near side is illuminated by the Full Earth. We on Earth see the retro-reflection from the moon's earthlit regolith layer (the so-called Ashen Light).
