Janos Mattis-Teutsch keeps values measured and balanced, a hallmark of tonal restraint. Janos Mattis-Teutsch builds on cool foundations: the palette favours the blue-cyan-green arc. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The highest-chroma note - #4C5D8B - appears at just 5.1%, deployed as a precision accent against the quieter ground. 45 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. These proportions encode Janos Mattis-Teutsch's instinctive sense of how much of each quality the eye can hold.
