Why the moon looks like the cloud-structure on the blue sky among the clouds?

The Moon is a dark gray in color -- it reflects light poorly but uniformly. (Its color is about the same as fresh asphalt! It's albedo is about 12%) Clouds are (usually) light gray with an albedo ranging from 10% to 90%.
Both the Moon and the clouds shine by reflected sunlight, so they're both the same color. (Clouds usually have a greater surface brightness owing to their lower albedo.)
The moon has dark and bright areas.
When it is visible in the daytime the bright areas appear roughly as bright as clouds, but the dark areas have no light to add to the scene and we are just left with the blue light from the sky generally.
The sky blue is not as bright as the clouds or the moon, at least when it's visible like this (typically near the end of day and early morning) so it does not conceal the bright clouds or the moon's brighter parts.
Sry Guys ;) english is not my main language so maybe i mesed in question :) still i think i found the answer , it serms everything on a blue sky would look cloudish ? My main concern was why moon looks more cloudish than clouds moonish ;) but now i think its just the contecst ;) Thx
