Otto Marseus van Schrieck is low-key throughout, a quality associated with Obsidian Cinder - deep shadows dominate the composition. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #060B0A at 63.5% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. At 1.3%, #DDD1AB carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 73 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Otto Marseus van Schrieck's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
