the color of the monsters should really match the color of the action they're taking. I get that that they can potentially pick a different action if you pick the same one as they do but it wouldn't be difficult to recolor them dependent on which action they took. Otherwise, the player has to purposely ignore your monster artwork and focus on the dots at the top of the screen.
