Values in Muralism rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. At 25.8%, #131423 functions less as a colour accent and more as a complete atmospheric environment. The saturated accent, #576B96, registers at 8.6% - sparse enough to feel like a deliberate surprise. The full value range is 70 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
