Gesina ter Borch sits in the centre of the value range, lending the palette a sense of even, sustained light. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 3.3% is devoted to #9E3B21, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 72 units of the value scale - a span that creates natural depth. This is the light Gesina ter Borch preferred, made measurable.
