Clouds are always bright

When undercover and in dark places when daytime and at a altitude where clouds are rendered, they are a bright white even though the surroundings are dark.

EDIT: the world type used to produce this bug is AMPLIFIED with the seed stated below
Also, to basically sum up the mumbo jumbo above, the lighting of the clouds don't react to the shadows, so when passing through a cave high up in a mountain (on amplified), the clouds are a bright white

Included in the attachments are a screenshot of the bug and my current settings for minecraft at the time
