Westvale Abbey in Commander

[Thanatos003]

Can I use Westvale Abbey's first ability to put a black white token on the field if I am using say a green white commander deck?

[Thanatos003]

Well damn. I thought since it didn't have a mana cost I could use it. Well that sucks gotta find a replacement land then.

If you look next just to the left of where it says legendary creature, on ormendahl. There is a black dot. This  signifies that ormendahl is black in color. It's mostly used on flip cards.

The new avacyn on her flip side has a red dot, for another example.

However, in general colors of created tokens are not considered in color identity. {batterskull} for example creates a black germ token, but has a colorless identity.
