This A6 greetings card features a vibrant design inspired by William Benson’s pioneering work on colour theory from 1868. Adapted from The Manual of the Science of Colour, the grid of coloured dots was originally used to explore how colours relate and interact. Restored and enhanced by Roomytown’s design team in Bath, UK, the artwork now has a joyful, confetti-like feel—perfectly paired with the word ‘Congratulations’ in elegant gold foil.
