Choosing a door colour is a matter of personal preference and the room's style. Lighter colours can create a brighter, more open feel, whilst darker colours add depth and drama. When selecting a door colour, it is important to consider the amount of natural light that enters the room. Ultimately, the ideal door colour should complement the overall room design and reflect the homeowner's style and taste. There is no rule stating that doors should be painted darker or lighter than the walls, and both can be painted the same colour if desired.
