Bartholomeo Bettera sits in the centre of the value range, lending the palette a sense of even, sustained light. Bartholomeo Bettera 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. Only 6.7% is devoted to #96391A, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 80 units: broad enough to build convincing three-dimensional form. This is the light Bartholomeo Bettera preferred, made measurable.
