Yes, you can take the keys off just by popping them with your fingers. No there no way to protect the letters. If you want them in black your best bet is to find black keyboard key stickers. Sometimes they come in glow in the dark although I don't know if they will have it for some of the mac keys.I want to spray paint the Apple Bluetooth keyboard. Just the keys.
Is it possible to take them off, and if so, any ideas on how to keep the letters from being covered?
