Emil Filla occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #99A543, is reserved to 5.0% of the surface, where it acts as a focal punctuation. 48 units of value spread create a palette that is varied but unified - contrast in the service of harmony. This is the light Emil Filla preferred, made measurable.
