Values in Giovanni Costa rest in the mid-range - neither dramatically lit nor steeped in shadow. Giovanni Costa builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The dominant colour, #191716, takes 39.3% of the total area, establishing the overall mood before any other hue is introduced. The highest-chroma note - #857141 - appears at just 4.8%, deployed as a precision accent against the quieter ground. The full value range is 71 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 3 of Giovanni Costa's sequence - a single chapter in a chromatic story told across many works.
