Painting in the bedroom should always display an object in a pair. Single object indicates loneliness. Display a beautiful pair of loving birds figurine or painting enjoying each other’s company. When it comes to decorating a house or bedroom, vastu says big No No to such objects or paintings. A painting or object may be unnaturally beautiful but to protect your happiness and harmony in a space, you should avoid putting up works which exude any negative feelings. Also, avoid wild animals in the house especially a bedroom. Replace lonely scene with the symbol or object that are paired, coupled, or romantic to make you space tuned in right frequency.
I agree with JHs. If there is no new color on it at all, just talk to the painter about it, if it was an honest mistake (which can happen very easily while painting) your painter should have no problem fixing it. However, in my years of experience, it is not unusual for 2 coats of door paint (good quality) not to cover very well at all. I once painted a red door 7 times, plus a tinted prime coat before I found the door to be a solid color.
