Mid-key values give Orphism its characteristic quietness - nothing blazes, nothing disappears. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 8.3% is devoted to #75704A, yet that small allocation delivers the palette's entire chromatic tension. Value range is moderate at 52 units - enough contrast for legibility, not so much as to fragment the tonal unity.
