Kozilek's Unsealing

Devoid (This card has no color.)

Whenever you cast a creature spell with mana value 7 or greater, draw three cards.

Modern Horizons 3

Devoid (This card has no color.)
Whenever you cast a creature spell with mana value 4, 5, or 6, create two 0/1 colorless Eldrazi Spawn creature tokens with "Sacrifice this creature: Add {C}."
Whenever you cast a creature spell with mana value 7 or greater, draw three cards.

A card with devoid is just colorless. It's not colorless and the colors of mana in its mana cost.

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.

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.

If you cast a creature spell with {X} in its mana cost, use the value of X that was chosen when it was cast to determine its mana value.

Kozilek's Unsealing's triggered abilities trigger before the spell that causes it to trigger. The ability will resolve even if that spell is countered or otherwise leaves the stack.

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.
