In Western culture the word "green" has several meanings and is most often used to describe someone inexperienced or envious, however, in other cultures "green" denotes growth, revitalisation and fertility. It is closely linked to the Old English word "growan" meaning to grow.
Green is also a very calming colour and works well as a colour for a feature wall or just as a splash of colour.
And of course, nothing beats a fresh lime to liven things up. This year we had so many limes on our tree that I made lime marmalade and gave it to my friends.
Green is good.
