Juan Luna distributes its values across the middle register, creating harmony without high contrast. Juan Luna balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #BB8544, is reserved to 5.0% of the surface, where it acts as a focal punctuation. At 54 units across the value scale, the palette keeps contrast readable without letting it dominate. These proportions encode Juan Luna's instinctive sense of how much of each quality the eye can hold.
