CliffordPope said:If you aren't going to be constantly using the switch or plugging and unplugging things - eg a kettle socket or a standard lamp - then ordinary paint works fine.
But if you think about how you actually insert a plug, then it would need to be a very tough paint not to quickly rub and chip around the holes, which looks horrible.

Both let you insert your own paint or wallpaper behind the clear faceplate. Both are priced accordingly.

It just looks wrong and draws the eye because in fine art terms the "ground" really matters because the way the light bounces of a surface is how we see it. We see colour because of the way light is reflected from it. Light reflects differently from a smooth plastic surface than a plastered surface. I'd opt for the clear plastic option, far more invisible than a colour match paint or plastic.
