Values in Joseph Bail rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The most saturated colour, #CE8C41, is reserved to 7.5% of the surface, where it acts as a focal punctuation. A value spread of 59 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light Joseph Bail preferred, made measurable.
