White walls cause eyestrain and coloured walls can evoke positive feelings. Having murals in public space is therefore good, but not inherently; murals are often made only for advertising purposes using unsustainable paints. They do not meet the needs of the community and the planet. By co-designing murals with the local community, using sustainable paints, art that reflects the beliefs of the public is brought to the public in an ethical way. When imagery of nature is then incorporated in the design the mural might also bring eco-therapeutical benefits such as improved mood, stress and anxiety relief. The goal is to make murals that promote better mental health without adding to our climate crisis.
