How do you make burnt umber acrylic?

To create burnt umber acrylic paint, start with a base of raw umber, which is typically a dark brown color. To achieve the burnt umber shade, mix in a small amount of red or orange pigment to warm it up, and adjust with black or white as needed to reach your desired tone. You can also use pre-mixed burnt umber acrylic paint directly from art supply stores for convenience. Always test your mixture on paper to ensure it meets your expectations before using it on a larger project.
