Charles Courtney Curran sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. 36.5% of the palette belongs to #181917, a concentration that makes it the unmistakable visual centre. #A36C34 delivers the chromatic peak at only 2.6% - a small shot of colour with outsized visual impact. The value range spans 62 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Charles Courtney Curran's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
