Muted is nice for sure. I own the original set. I also own GMK classic retro (beige/9009, you know… that one). There is certainly a spot where you could have something nice that falls between the two in terms of colors.
Muted looks fantastic on most boards, but I feel like it loses something on certain grays. It just looks too washed out. I think that’s where this new colorway will work well.
I think the pairings will go well like this:
GMK Classic Retro for silver and polycarbonate boards
GMK Muted for boards with soft tones like blue-gray, lavender, rose gold or white
Muted Retro for gray and black cases
