AP controls a creature with Devoid (say, Nettle Drone), then casts Humility.
If I get it right, DoH is then a 1/1 creature that doesn't have Devoid but is still colorless (nothing gives it a new color).
What if AP then has a Clone ETB as a copy of DoH ? Does it copy the “colorlessness” of DoH, or does the game “recompute” the color of Clone>Nettle Drone due to it having a mana cost of 2R and no Devoid to remove its color ?
(Don't know if I made myself very clear, sorry if that's not the case :/)

Hello,

When you copy a card, you copy the card as printed (and as modified by other copy effects). You don't take effects like Humility into account when you're figuring out the copiable characteristics of the card. When you're copying the Drone, you're also copying the fact that it has devoid (even though it currently doesn't have it due to Humility). The Clone Drone will also be colorless, not red (remember that we apply color-changing effects in layer 5 before we remove abilities in layer 6).
