Reply to Different coloured Traktor X1s

Has anyone else got a pair of X1s that don't match?

The first one I brought (brand new) has dark blue colour buttons and it matches the colours on my Maschine but the second one I brought (second hand) has turquoise/light blue colour buttons. I'm not sure if I'm missing an option to change the X1s colours or if I just have two different models...
