All Is Dust

Tribal Sorcery — Eldrazi

Each player sacrifices all permanents they control that are one or more colors.

A colored permanent is a permanent with at least one colored mana symbol in its mana cost. Note that effects may cause a colored permanent to become colorless (as Moonlace could), or a colorless permanent to become colored (as Crimson Wisps could).
2010-06-15:
Tokens may also be colored permanents. The effect that creates a token states what color it is or whether it’s colorless.
2010-06-15:
Lands have no mana cost, so they are colorless unless an effect states otherwise.
2010-06-15:
All the colored permanents are sacrificed at the same time.
2013-07-01:
All Is Dust doesn’t destroy permanents. Rather, it causes them to be sacrificed. Regeneration, totem 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.
