Devoid (This card has no color.)
: Adapt 1. (If this creature has no +1/+1 counters on it, put a +1/+1 counter on it.)
Whenever one or more +1/+1 counters are put on this creature, you may create a 0/1 colorless Eldrazi Spawn creature token with "Sacrifice this token: Add 
."

Other cards and abilities can give a card with devoid a color. If that happens, it's just the new color, not that color and colorless.
Devoid works in all zones, not just on the battlefield.
If a card loses devoid, it will still be colorless. This is because effects that change an object's color (like the one created by devoid) are considered before the object loses devoid.
Devoid doesn't affect the color identity of the card for the purposes of the Commander variant. For example, while Abstruse Appropriation is colorless because it has devoid, its color identity is still white and black, and it can't be included in a Commander deck where the commander's color identity doesn't include both white and black.
If a creature somehow loses all of its +1/+1 counters, it can adapt again and get more +1/+1 counters.
You can always activate an ability that will cause a creature to adapt. As that ability resolves, if the creature has a +1/+1 counter on it for any reason, you simply won't put any +1/+1 counters on it.
A card with devoid is just colorless. It's not colorless and the colors of mana in its mana cost.
