The colour logic of interior is concentrated here: its characteristic value range, temperature bias, and chroma level. Values in interior rest in the mid-range - neither dramatically lit nor steeped in shadow. Warm hues command this palette; it favours the reds, oranges, and yellows of firelight and earth. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #526AB4 - appears at just 1.7%, deployed as a precision accent against the quieter ground. The value range spans 59 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Applied to contemporary work, these proportions immediately evoke the interior register.
