Roomy Town Framed Oak Print - Nomenclature of Colours In 1886, Ornithologist Robert Ridgway sought to standardise and catalogue the various shades and tints of colours named in the descriptions of birds for professional and amateur naturalists. Several decades after he published his first book, Ridgway went on to create another volume, covering more than a thousand colours. His work continues to bring value to naturalists and artists who, a century later, still use his work as a standard reference. Roomytown's designers used Ridgway's impressive display of colour swatches to curate this stunning fine art print. This stunning print by Roomy Town is printed on museum-grade paper and comes ready framed in a simple natural oak.
