The ultimate feeling it creates is one of rest.

[Footnote: Supernatural rest, not the earthly contentment of
green. The way to the supernatural lies through the natural. And
we mortals passing from the earthly yellow to the heavenly blue

horizontal movement ceases; likewise that from and towards the
centre. The effect on the soul through the eye is therefore
motionless. This is a fact recognized not only by opticians but
by the world. Green is the most restful colour that exists. On
exhausted men this restfulness has a beneficial effect, but after
a time it becomes wearisome. Pictures painted in shades of green
