Values in Henri Martin rest in the mid-range - neither dramatically lit nor steeped in shadow. Henri Martin balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #606B47, is reserved to 8.2% of the surface, where it acts as a focal punctuation. The value range of 47 units sits in the comfortable middle: enough depth, enough light, neither extreme. In the context of Henri Martin's full range of palettes, group 15 represents one movement in an ongoing chromatic dialogue.
