Antonio Jacobsen is high in key: pale, luminous, and filled with optical air. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Mid-saturation across the board: the palette has colour character without chromatic excess. Only 10.5% is devoted to #63A7EB, yet that small allocation delivers the palette's entire chromatic tension. 45 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 6 of Antonio Jacobsen's sequence - a single chapter in a chromatic story told across many works.
