Sheer Drop

If a spell with awaken has multiple targets (including the land you control), and some but not all of those targets become illegal by the time the spell tries to resolve, the spell won’t affect the illegal targets in any way.

Awaken doesn’t give the land you control a color. As most lands are colorless, in most cases the resulting land creature will also be colorless.

The land will retain any other types, subtypes, or supertypes it previously had. It will also retain any mana abilities it had as a result of those subtypes. For example, a Forest that’s turned into a creature this way can still be tapped for {G}.
