Masking their eye color has already been shown to happen by both Derek and Peter. In S1, as indicated with Bennett's avatar, you can clearly see that Derek's eye color was yellow. In S2 they were Alpha red, but then in Visionary we learn they were blue since Paige and we get the scene where Alpha Derek looks up to the sky and we see that his eyes are really blue. Peter in S1 had the red eyes of an Alpha but in S2 and until Visionary in S3, his eyes were yellow as a Beta. During the telling of the flashback story in Visionary, Peter's eyes glow cold blue as well. This is either another continuity f-up or proof that they can mask their eye color.
