Identify the element: black-and-white line spectra with blank labels

An example figure from the Line Spectrum generator.

Three line spectra drawn as black lines on white, each with a blank line in place of the element’s name — Three line spectra, mercury, neon and helium, printed as black lines on white for a black-and-white copier, each with a blank line where the element’s name would be. Students match the line positions on the 400 to 700 nm scale to a reference chart to name each element.
