Theophile Steinlen occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 2.9% is devoted to #BAA06A, yet that small allocation delivers the palette's entire chromatic tension. 72 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Theophile Steinlen's palette 10 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
