Visualization of element spectra

These are the visualizations of element spectra in the range 400 - 700 nm. Lines are according to NIST atomic spectra database. Elements are sorted alphabetically. If some element is missing, like for example Fr, then that element has no lines in the visible range. Most of the trans-uranic elements are missing from the list due to their nature (short lifetimes, unknown spectra) or due to my laziness. Spectra here shown are made after normalization to strongest line and after the eye-sensitivity was accounted for. All spectra are available for free (in good faith that you'll specify the source). Any feedback (even bad :( ) is appreciated. You can click on an image to see its larger version. Warning: this spectra is basically illustration how emission spectrum of these elements looks like when they are in gaseous state, and have electron temperature of 1eV. That has almost nothing to do with their color when they are in solid state. If that confuses you I recommend checking the wikipedia about it, and I found these sites to be pretty good in explaining why are certains things colored the way they are and how to calculate that.

This is the "calibration" image, line on every 10nm.

This is the spectrum of a water vapor in the radiofrequent plasma, 300W, frequency 13.56 MHz. Hydrogen alpha, beta and gamma lines are strong (Balmer series).
