Could the player-visuals in Morde's ult be a little more bright?

I don't know about anyone else but most of the time when I ult someone as Morde I don't even notice any of the...'spirits' (?) of other players moving around, including my own teammates and often find myself surprised as to where everyone has gone. Even when seeing Morde ult from the outside perspective, the two little soul orbs moving around seem pretty muted

Could we make them brighter and more noticeable?
