So when it comes to home decorating, one coat of paint is all that is needed. Those with any interest in art and DIY will paint as we do. Those without any interest will use magic to get the paint on the wall. (Get the spell wrong though and that paint can end up anywhere. Water can be bad enough here, just ask the Sorcerer's Apprentice.).
The Queen's Palace has rooms in every shade imaginable. Roxannadrell loves colour and has been known to change her gown so she blends with whatever room she is in. (A quick tap with her wand ensures the change is painless and convenient). Occasionally this can make the monarch difficult to find! (She has been known to do this deliberately when she decides she really cannot face the Council again).
