I just sent in my response, and I want to add on to ullr's opinion that while I do prefer the grey mods, I also don't have a huge issue with the current colored mods for the keyset. On one hand, it is nice to differentiate GMK Penumbra with SA Penumbra; on the other hand, the colors seem a little too vibrant on the keys. However, because my order is on its way to me, I guess I shouldn't make a judgment call based off a few photos online.
