Henri Matisse occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. #629853 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.8%). 53 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 29 of Henri Matisse's sequence - a single chapter in a chromatic story told across many works.
