Here are visualizations of element spectra 400 - 700 nm according to NIST atomic spectra database. They are sorted alphabetically. If some element is missing, like for example Fr, then the element has no lines in visible range. Also, most of the trans-uranic elements are missing. Spectra here shown are made after normalization of strongest line and after eye-sensitivity was accounted for. Ac
