1798–1866
A Scottish artist, interior decorator, and color theorist, he brought practical craftsmanship and big ideas together in books on design, proportion, and ornament. His work linked everyday decorative practice with larger theories about beauty, harmony, and architecture.

by D. R. (David Ramsay) Hay
Born in Edinburgh in March 1798, David Ramsay Hay built his career as a decorative artist and writer on art. Reliable biographical sources describe him as a Scottish artist, interior decorator, and colour theorist, and note that he developed a strong interest in the principles behind design as well as its practical execution.
Hay was associated with major decorative projects in Scotland, including work connected with Abbotsford and Holyroodhouse, and he became known for writing about colour, proportion, and ornament. His books explore how visual harmony works in architecture and art, which helps explain why his name still appears in discussions of nineteenth-century design theory.
For audiobook listeners, he is best approached not simply as a craftsman, but as a lively nineteenth-century thinker who wanted to explain why beautiful design feels balanced and convincing. His writing sits at the meeting point of art, architecture, and theory, making it especially interesting for readers curious about how artists once tried to turn beauty into a science.
