If viewing a cloud from an airplane above it on a sunny day, what color would the top likely appear, contrasting with the dark base seen from the ground?

Answer

Brilliant white

When viewed from above, the top of the cloud is likely to be seen catching the sun, appearing brilliantly white, which highlights that the perceived blackness is an artifact of the viewing angle relative to the thickness of the moisture column.
