David Alfaro Siqueiros sits in the centre of the value range, lending the palette a sense of even, sustained light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #2E4E79, registers at 5.9% - sparse enough to feel like a deliberate surprise. The palette spans 52 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of David Alfaro Siqueiros's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
