Rubens Santoro keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #251C14, is reserved to 4.8% of the surface, where it acts as a focal punctuation. 59 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Rubens Santoro's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
