What card is unhinged... and champ im sorry to say your wrong on that. from the edh website:

A card's colour identity is its colour plus the colour of any mana symbols in the card's rules text.
The Commander's colour identity restricts what cards may appear in the deck.
Details

Cards
in a deck may not have any colours in their identity which are not
shared with the commander of the deck. (The identity of each card in
the deck must be a subset of the General's) Lands whose type
includes swamp, island, plains, forest and/or mountain (e.g.: basic
lands, shocklands, dual lands, Shadowmoor special-basics, etc) DO
contain the corresponding mana symbol(s) as per CR 305.6. As such,
while they are "colourless" they do have a colour identity and may not appear in a deck unless the Commander is of the appropriate identity.
While hybrid mana symbols may be played with either colour
mana, they contribute both colours to the card's colour
identity. Therefore they may only be played with a Commander
whose identity includes ALL of the hybrid symbols' colours.
Basic land words (swamp, forest, etc) in the
text box of a card do NOT represent a coloured mana
symbol. They are not restricted to Commander of the same
colour identity.
Reminder text is not included in the colour identity of a card.
