These are (OLD) visualizations of element spectra in the range 400 - 700 nm. For new version where they are sorted in periodic chart and in higher resolution please go to the main page.

The 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: these spectra are basically illustrations how emission spectrum of these elements looks like when they are in the state of plasma. 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 a "calibration" image, line on every 10nm.

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