Spectra of Gas Discharges
Color spectra of elements undergoing electrical discharge excitation.
Image "screen shots" are from an applet which computes and plots the spectra in a web browser window. The JPEG images below are not dithered. They may appear so if your display doesn't have enough colors to represent the entire color range. Displays limited to 256 colors or less don't produce acceptable spectra. Try increasing your color resolution to 16 or 24 bits (16 million colors).
