It is a colour that is difficult to manage in decoration. That’s why it’s generally advised to use it in small touches: cushions, vases, paintings… In my opinion, it’s a pity because we deprive ourselves of its benefits.
As we have seen, red brings dynamism, passion, and helps to move into action. There are therefore rooms where red walls are quite appropriate: offices, co-working spaces, sports rooms… But it also has its place to energise a corridor, an entrance hall, the dining room and even the kitchen as it whets the appetite!
However, it is not recommended for bedrooms, other than in light touches.
In general, be careful not to overdo it either, as this could bring out the aggressive side of red. For example, you can adopt the solution of the painted half-wall: the upper part is painted red for example, and the lower part is reserved for more neutral colours such as grey, beige or linen.
Red goes particularly well with blue for a warm-cool effect and the pure contrast of two primary colours.
Red likes green, which is its complementary colour on the colour wheel. Red awakens green, which calms red. It is a balanced association.
The colour orange can be combined with red to create a harmonious and dynamic combination of two warm colours.
Finally, red and violet can be combined to create intimate, luxurious spaces.
