This program converts spectra to different color coordinates. Use cut, copy and paste functions to move color spectra from text file or program to the spectra window below. You can use example spectra, if you don't have your own. You can choose light source and color-matching system, which you want to use for calculating color coordinates. NOTICE, that the wavelengths (inside colorimetric range 360nm - 830nm) must be in the first column and the color spectra values in the other ones, each in their own column.
