“Blue and Green should never be seen” (because the colours clash), is a saying about colours (not) to wear together, but as Nature proves there is nothing wrong with these two colours side by side – in fact they create harmony and tranquillity and can even help to reduce high blood pressure. So if you are feeling a little stressed find yourself a green space, preferably with a blue sky, and relax!

I remember that saying and thinking how silly it was. Nature knows best!
Oh! For real? There goes my entire wardrobe then. š Nature always knows. The view up to the blue sky or towards the sea through the pine needles is my favourite colour combo.
