If you’ve taken a painting class you’ve likely had to create a color wheel. When the date of this color plate caught my eye (1830) I did a little research. Charles Hayter was a well-known miniature portrait-painter and teacher who lived in London. He taught Princess Charlotte, the granddaughter was appointed to the court of King George IV, published, exhibited and taught. In 1830 he published A New Practical Treatise on the Three Primitive Colours.
The cool thing is the Practical Treatise is available in its entirety at OpenLibrary.org. Have a look—the book is 183 years old. There, art class is dismissed for the day.
