SpectraChroma is a program that calculates and plots the color coordinates of emission spectra in the CIE 1931 Chromaticity Diagram (2 Degree Standard Observer). Features: Import multiple spectra at once Automatic data labeling Can save the Chromaticity Diagram in several image formats (including SVG, PNG, JPG, TIFF) Chromaticity Diagram customization by showing/hiding the axes, grid lines, and data labels Display the CIE color coordinates and the calculated perceived color Export all CIE color coordinates and the perceived colors to Microsoft Excel or plain text The zipped Windows and Linux releases of SpectraChroma already include all dependencies and can be executed without installation, just unzip their contents and run the program. There is also an (optional) Windows installer that installs SpectraChroma and its dependencies. SpectraChroma was developed in Python (version 3.9.4). It is worth noting that even though SpectraChroma was written in Python, no Python installation is required to run the SpectraChroma executables. The latest releases (with the executables) can be found on: https://github.com/tbpaolini/spectrachroma/releases.
