Colours for the home inside & out vary greatly. A lot depends on taste but also especially indoors on which way the house is facing.
North facing rooms tend to be colder & have less light, so a yellow or cream light colour would suit more than green or grey. Or you could use dramatic colours like purple & work with it, not fight nature with it being a dark room.
South facing rooms have light all day long so warm or cool colours work, the choice is yours. Pale tones keep it light & airy, blue for a seaside feel or white for a crisp feel.
East facing rooms, the light can appear slightly blue so blue or green would work. To create light & warmth, duck egg blue is a good choice
West facing rooms would be enhanced by using a white palette to make a wonderful airy feeling in the natural or artifical light. A soft pink would create a warm glow
**Black can be hard to use indoors, but is a popular colour in contemporary homes & looks great with red for a dramatic dining room**
