▸ The reading
interpretive · artVan Gogh's sunflowers and Matisse's reds are cadmium readings — its sulfide pigments made the most vivid palette of the modern era, with a toxicity the era hadn't yet priced in. It now layers thin-film solar cells and lingers in fading NiCd packs. Brilliance and hazard sharing one electron shell.
The science below is cited as science; the symbolic layers are flagged as interactive art.

▸ Stellar origin
s-process in AGB starsPredominantly slow neutron capture in helium-burning shells of dying low-mass stars. Earlier Matter data overstated the r-process contribution.
▸ Reactivity
Forms intense yellow and red sulfide pigmentsCadmium yellow and cadmium red were van Gogh's favored pigments — vibrant, lightfast, and quietly toxic.
▸ Applications
- Nickel-cadmium rechargeable batteries (declining)
- Cadmium-telluride thin-film solar cells
- Yellow and red pigments (artist's colors)
- Neutron-absorbing control rods
▸ Curiosity
Van Gogh's sunflowers and Matisse's reds came from cadmium pigments — the same toxicity that worries us now made the most vivid colors of the modern era.
