Greens are the new blues and greys, greens are everywhere and I can understand, as it is such a lovely colour of life. Fresh, calming and at the same time energising. I am not the fan of apple green colours, as they are usually a bit too bright, that you can can get tired, as well as it is very hard to mix apple green with any other colours. However, shades closer to emerald colour are working perfect. Not a fancy of rich colours? Go pale green, as it will work just as fine.
