1798–1866
A Scottish artist, interior decorator, and color theorist, he turned practical design work into clear, ambitious writing about beauty, proportion, and harmonious color. His books connect art, geometry, and architecture in a way that still feels curious and original.

by D. R. (David Ramsay) Hay
Born in Edinburgh in March 1798, David Ramsay Hay built a career that joined hands-on decorative work with serious thinking about art. He trained as a painter and decorator, and later became known for interior work connected with major Scottish settings, including Abbotsford, the home of Sir Walter Scott.
Hay is remembered above all as a writer on color, form, and proportion. His books explored how harmony in design might be understood through underlying principles, and he wrote on subjects ranging from coloring and beauty to architectural form and the proportions seen in Greek art.
He died in September 1866. Although he worked in the world of interiors and decoration, his writing gave him a wider legacy: he helped turn nineteenth-century design practice into a subject of theory as well as craft.
