charcoal only in UK any silver bezelled units are EU imports so beware........ but if you really want a silver UK one it can be done speak to MAW (can have pink with purple spots if you want)
I'd avoid spraying anything with its still attached to the chassis - the chances of not getting paint sucked into the innards are NIL; and do you really want sticky tape on the front filter!
Its relatively straightforward to repaint the bezel - though stripping the bezel off the chassis takes a while.
You'll need a Pedestal stand on hand too - as without the bezel you have the pixel array glass 'unprotected' and the chassis cant stand up in its box without potential damage to the display.
Possibly best left to someone who's done it a few times.
