Karel kréta keeps values measured and balanced, a hallmark of tonal restraint. Karel kréta builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 26.5%, #292929 functions less as a colour accent and more as a complete atmospheric environment. The most saturated colour, #79583C, is reserved to 4.7% of the surface, where it acts as a focal punctuation. Value range is moderate at 54 units - enough contrast for legibility, not so much as to fragment the tonal unity. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 4 sits within the larger chromatic argument that Karel kréta's complete body of work advances.
