Pierre-Narcisse Guerin distributes its values across the middle register, creating harmony without high contrast. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #A53422, is reserved to 2.7% of the surface, where it acts as a focal punctuation. 58 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Taken together, these qualities constitute Pierre-Narcisse Guerin's chromatic voice - distinctive enough to be read across an entire body of work.
