Mid-key values give Vilho Lampi its characteristic quietness - nothing blazes, nothing disappears. 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. A single dominant - #252624 at 26.5% - sets the character of the whole composition. The saturated accent, #907B54, registers at 3.8% - sparse enough to feel like a deliberate surprise. A value spread of 61 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Vilho Lampi's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
