Orange is decided to be a very hot color. It is like fire, makes you feel warm. This color can be associated with a hot summer sun or with the autumn when the leaves change their color. Orange color, when it is profitably set, can add warmth to every space.
Red and green are usually not recommended to combine in the interior, because both colors are naturally contrasted. But still, they look cool, especially in summer, when brave shades are welcome. Red and green combinations are perfect for different interiors: Modern, Medieval, Marocco and many others.
