Jan Joest distributes its values across the middle register, creating harmony without high contrast. Yellow, ochre, sienna: warm hues that Jan Joest deploys as the palette's primary energy. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #603A24, registers at 8.6% - sparse enough to feel like a deliberate surprise. The value range of 53 units sits in the comfortable middle: enough depth, enough light, neither extreme. Palette 4 sits within the larger chromatic argument that Jan Joest's complete body of work advances.
