Values in James Webb tilt decisively toward white, giving the palette its luminous character. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Mid-range chroma keeps the palette grounded - colourful but not strident. #805B2E delivers the chromatic peak at only 6.2% - a small shot of colour with outsized visual impact. At 58 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 6 of James Webb's sequence - a single chapter in a chromatic story told across many works.
