Activate (color) when no color on board

Can't tell if this is intentional or not, but seen it a lot now thanks to the Ingest mechanic. With cards that are Activate X <color>, if there are no gems on the board of that particular color, it will just make X random gems become activate gems (instead of, say, no gems).

For example, Honored Heirarch is Activate 3 Green, but if the board is devoid (pun intended) of Green gems, he'll just turn 3 random gems of any color into activate gems to grant 5 extra mana.
