Ruinous Path

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.

If the non-awaken part of the spell doesn’t require a target and you cast the spell for its awaken cost, then the spell won’t resolve if the target land you control becomes illegal before the spell resolves (such as due to being destroyed in response to the spell being cast).

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.
