Balthasar van der Ast occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Yellow, ochre, sienna: warm hues that Balthasar van der Ast deploys as the palette's primary energy. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #9B7D4E - appears at just 2.9%, deployed as a precision accent against the quieter ground. At 49 units across the value scale, the palette keeps contrast readable without letting it dominate. Balthasar van der Ast's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
