Copper — Spectra Tee
Made to order — printed and shipped in 2–7 business days.
Copper turns flame blue-green. The lines cluster between 510 and 578 nanometres a narrow, cool band that separates it at a glance from the reds and yellows of the alkali metals.
Printed to scale on black cotton, the wavelengths hold their true positions, each rendered in the colour it emits. Front placement, soft-hand finish.
Spectra reads matter by its light. Copper is the metal that carries current in nearly everything electric, named for the island where it was first mined at scale.
