It struck me that among the colour combinations available in the Pentax Q-S1 Color Simulator, a sort of gunmetal gray was an option for both the top plate and the lens barrel. So I went to recreate a Q-S1 with as close to the colour scheme of a Pentax K-3 Prestige Edition as I could. It made me think that gunmetal gray might become a colour option that we’ll see in Pentax products more often after this point. I have to admit it looks sleek.
Updated 2014/08/28: There are two other recent grey models from Pentax/Ricoh, one being the limited edition Ricoh GR and the other a grey K-S1, just announced. The K-S1 colour is called “tweed grey”. Officially, the GR edition is green.
