Prussian blue is the key to getting the right tonality and hue for a green that can just as easily be called blue – just like the sea. It is a superb wall colour as it combines the clarity of blue with the balance of green; calm enough for a bedroom but lively enough for a family room. The Sea makes up 70% of our planet, a vast space filled with fascinating biodiversity, our natural wall paint recipes make sure we do not use any plastics or micro plastics that could end up in our great oceans.
