Painters today have more pigments to choose from than any other artists in history. They can buy traditional, historical varieties that Rembrandt would recognize, such as siennas and ochres, or 20th-century innovations like phthalocyanines and quinacridones—pigments with an intensity that would have startled even the color-loving Impressionists. Despite this abundance, many artists and art educators endorse the use of a restricted “limited” palette as a way to develop coherent, harmonious, and personal paintings.
“A painter’s palette is, ultimately, an expression of how they see the world and the colors that they love. By exploring a variety of limited palettes from earthy to intense, painters can discover the combination of colors that best helps them convey their world view.”
