Jacoba van Heemskerck occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Jacoba van Heemskerck orchestrates warmth above all else - reds, ambers, and siennas take the lead. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #815338, covers 3.7% of the surface: too much to call an accent, too strong to ignore. 57 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Jacoba van Heemskerck's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
