Yes, a faded teal would be more correct, but I really do hate teal. And I'm metro enough as it is without gadding about with pink devices, thank you very nice.

I still like this combination, as disconcerting as indigo can be (but notice how the background validates your cream/beige idea):

I think you can get away with more variation if you pick a textured leather (as you've done). Then the nuances of color can be a tad more forgiving, and off-match matches attain a tad more contrast.
