Add to that the Blue Boy by Thomas Gainsborough at the Pasadena Huntington and anything by Hans Holbein the Younger such as the portraits of Sir Thomas More and Thomas Cromwell at the Frick Collection.

The former uses a brilliant blue paint that is simply impossible to convey via RGB display or CMYK printing color spaces and the latter look like giant printed photographs, down to the stubble on More's face, even though they were painted in the early 16th century.

I'm sad that people don't bother with that as much today. I went on a shopping spree a while ago buying a bunch of Williamsburg and Old Holland oil paints and their colors are absolutely amazing, especially the old school heavy metal paints which come in a variety of opacities. Blending them is an art in its own right. Sadly I don't have any skill at painting so it's mostly abstract experiments with color.
