Values in Constantin Guys rest in the mid-range - neither dramatically lit nor steeped in shadow. Yellow, ochre, sienna: warm hues that Constantin Guys deploys as the palette's primary energy. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The highest-chroma note - #FECB68 - appears at just 1.2%, deployed as a precision accent against the quieter ground. 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This is palette 4 of Constantin Guys's sequence - a single chapter in a chromatic story told across many works.
