Lands have no mana cost, so they are colorless unless an effect states otherwise.

Tokens may have one or more colors. The effect that creates a token states what color it is or whether it's colorless.

All permanents with one or more colors are sacrificed at the same time.

All Is Dust doesn't destroy permanents. Rather, it causes them to be sacrificed. Regeneration, umbra armor, and indestructible can't save permanents from All Is Dust.

A land card that produces colored mana, even a land with a basic land type, normally has no color.

This cards was originally printed with the "tribal" card type. That card type has been replaced with "kindred". This change does not affect the gameplay function of this card.

While it appears only on cards that already have other card types, kindred is a card type and will be counted by effects that refer to the number of card types among cards in a zone.

Kindred is a card type that allows noncreature cards to have creature types. For example, Echoes of Eternity is an Eldrazi (although not a creature) while on the battlefield and an Eldrazi card (although not a creature card) in zones other than the battlefield.
