Although it seems obvious to say it, the bedroom is the space in the house for rest and relaxation. Therefore, when decorating it, we must think of a color that encourages us to do so, not that it is so strident that it prevents us from relaxing.
It is evident that there are bedroom decorations in bright colors such as red that are wonderful on an aesthetic level, but if we think about creating a suitable environment for a bedroom is much better that we decide on cold tones, like blue in its different versions.
In fact, blue has become this season's trend color for bedroom decoration. Its degradations are easily combinable, since the brightest tones can be placed on walls with little light while the dark ones are great near the windows, to take advantage of their reflection.
Also, blue is a color that combines perfectly with black and white as a complement. Also, how cold it can sometimes be can be counteracted with warmer blues in the curtains and pillows. You can even incorporate blue into the ground, either on the floor or on the carpets, always combining it with touches of white or black.
Clearly, blue is not an easy color to fit everyone's tastes, but when used to accentuate your décor, it can end up adding a very professional touch to your bedroom space.
