Bertalan Por occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #D0B968 - appears at just 6.0%, deployed as a precision accent against the quieter ground. At 62 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Bertalan Por's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
