Mario Eloy occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #224634, is reserved to 5.9% of the surface, where it acts as a focal punctuation. The full value range is 55 units: broad enough to build convincing three-dimensional form. These proportions encode Mario Eloy's instinctive sense of how much of each quality the eye can hold.
