Ferdynand Ruszczyc keeps values measured and balanced, a hallmark of tonal restraint. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #496BA2, is reserved to 4.7% of the surface, where it acts as a focal punctuation. Spanning 47 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Ferdynand Ruszczyc's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
