Dan Gerhartz Teaches "Cool Sandwich" Color Temperature Principle on The FASO Show

On September 10, 2026, artist Dan Gerhartz appeared as the featured guest on The FASO Show in an episode titled "Demystifying Color Temperature: Discover the Cool Sandwich." Gerhartz, a FASO Signature Artist and founder of the teaching membership Sharing the Journey, presented his "Cool Sandwich" principle, which describes how color temperature shifts across form: a light plane saturates, then cools, then warms again, with the deepest shadows always warm. He demonstrated the pattern in both warm-light and cool-light portrait paintings, using references of his daughter Anna at ages 14 and 23. Gerhartz cited masterworks by Bouguereau, Sargent, Sorolla, Monet, and Emil Carlsen as examples, including Sargent's painting at the Crystal Bridges Museum of American Art in Arkansas. He explained his painting medium—four parts Gamsol, one part stand oil, and a splash of Damar varnish—and noted his studio uses 5,500K balanced light for the canvas and a 2,700K bulb for warm-light setups. The episode included a Q&A addressing halftones, reflected color, and observation exercises. FASO, a website-building service for artists, offered a $99 first-year membership through Gerhartz's affiliate link. The session was hosted by Olya Konell and Angela Agosto, with closing remarks from FASO founder Clint Watson.
