Probably fine, here is mine. Though IMO, it is better to keep the macro, Function keys and big sized keys of your numpad black to balance out the oddity...

Yeah I suppose I could keep a sort of border, like the bottom row black, macro keys black, top function keys black and the enter, + and - numpad keys black. Oh and probably left shift keys etc black because of the caps key.
Thanks for the help :) Going to buy white keys and play around with the design myself.
Which option for the letter engraving should I have so that it almost looks blank, but if you look close you can still see what it is?
