You won't know until it ripens - the unripe color doesn't mean anything. Think of this: I have varieties that range from that pale green to a kelly green, to a deep green, to purple when unripe, yet all turn red. Of course, I have other varieties that turn other colors, but again, the preliminary color doesn't really mean anything. However, I will tell you that most that become yellow or orange are also light green like that when unripe.
