What color would an astronaut view clouds as when looking down at them from above during a sunset?

Answer

Pure, blinding white

An astronaut viewing clouds from above, looking down at the unscattered sunlight reflecting off the cloud tops, would see them as pure white because they are viewing the light before significant atmospheric filtering affects the illumination source.
