Melchor Pérez de Holguín sits in the centre of the value range, lending the palette a sense of even, sustained light. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #591D18 delivers the chromatic peak at only 3.3% - a small shot of colour with outsized visual impact. The value range of 48 units sits in the comfortable middle: enough depth, enough light, neither extreme. This is the light Melchor Pérez de Holguín preferred, made measurable.
