Graphenstone, the world's most certified eco paint, has launched two new colours for Spring Summer 2023 - Serpentine blue, a soft chalky blue inspired by the trend for wild swimming and Baked Clay, a deep oxide red reminiscent of sun-baked Moroccan earth. Betsy Smith, Graphenstone colour consultant, created the new hues to perfectly harmonise with the existing Graphenstone core palette of 96 house colours.
