Jankel Adler sits in the centre of the value range, lending the palette a sense of even, sustained light. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. #703614 at 4.8% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. Spanning 44 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. Palette 4 sits within the larger chromatic argument that Jankel Adler's complete body of work advances.
