The relaxing Green (color)
Green is probably the one color that I can look directly at the longest. It is soothing to the eyes hence it is the color that is associated with life. Basically, it's the color that helps us stay calm since it's the color being associated with nature.
So, if you want a room to be a place of relaxation, the good choice would be Beige Green & Yellow-Green. These are the variation of the green color that looks more natural to the eyes. In most cases, the colors are the ones that make the space by giving it life.
