i got the white on black firstly, it's a little dull however i do prefer a clean look overall for a bigger size keyboard, due to the 20% discount i immediately bought the black on wht and the zero division set, so i can mix and match.
i think if the side facing the bottom of the keyboard is also clear/translucent then it would be much better, esp for rgb (or maybe on a whte on wht keyboard). as the clarity tends to be more opaque/darker than on the clear side.
i would like to see offering more colors with this more simplistic design, like a emerald green or a midnight purple or a shine through version, or able to do different colors with the font, then it could be really easy and simple, easy keycap sets that match a lot of styles (and can mix and match).
sometimes the themed keycap sets although nice, have too many graphics and symbols - im not a fan of those.
