Values in Anna Ostroumova-Lebedeva tilt decisively toward white, giving the palette its luminous character. Temperature is cool-dominant, with blue and green families claiming the largest areas. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 2.4% is devoted to #436663, yet that small allocation delivers the palette's entire chromatic tension. Value range is moderate at 39 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of Anna Ostroumova-Lebedeva's sequence - a single chapter in a chromatic story told across many works.
