Lithium — Spectra Tee
Lithium burns crimson. Two lines carry nearly all of it: 610.4 and 670.8 nanometres, the flame-test signature that tells a chemist what's in the sample before any instrument confirms it.
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. Lithium is the simplest metal one proton past hydrogen's shell, and the first element light enough to leave Earth's early atmosphere.
