Blue

All variants of the colour blue create the same kind of experiences in a room.
The soft ones a little more subtle and the intense, of course, a bit clearer. The main influences they can bring to a space are a sense of calm, serenity, refreshment and spatial enlargement. Both the blue tones and the cool neutrals from the blue colour chart create a number of important psychological associations in an environment. Namely, the creation of a reliable appearance and promoting concentration.
