If you are interested in color and meaning, then green is a symbol of nature, hope and harvest, and has a relaxing effect.
I present my choice in green color.
Green matches purple, gray, yellow, over green it brings to mind the freshness of leaves, trees and grasses.
Green is considered the most calm color for the eye, that's why we feel so good in nature, walking on green meadows. Green helps relieve stress, helping people to relax
