Green - is most the popular color at designers as it symbolizes the nature and life. It is the easiest color for eyes, its overabundance does not influence negatively mentality, and it can improve vision! It is the calming and freshening color, giving new vital forces and stimulating protective forces of an organism. For this reason the majority of hospitals are painted from within in green color (it is a pity, that frequently the vilest shade!).
Yellow - is the invigorating color of the sun. It draws attention even more, than red or orange color. And though it is considered as optimistically color, it is not so cloudless at all. On perception it is the most difficult for eyes color, and its surplus negatively influences mentality. It is proved, that in a yellow interior people are more often irritated, and children cry. Therefore do not hasten to paint a nursery entirely in yellow color! Though in the moderate quantity yellow can develop intellectual and artistic abilities.
Violet is a calming and harmonious color with elements of spiritual contemplation and mysticism. It symbolizes transition of one quality into another. If you need to change vital situation, violet is precisely your color.
