Andrei Rublev keeps values measured and balanced, a hallmark of tonal restraint. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The most saturated colour, #E6DAB4, is reserved to 4.0% of the surface, where it acts as a focal punctuation. 63 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Andrei Rublev's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
