ColorBySpectra Software

  • ColorBySpectra makes the tedious, multi-step process of converting raw UV-Vis spectra to color spaces easier than ever, with as few as three clicks. Simply select your data, choose a light source, and let ColorBySpectra handle the complex math to calculate color. With ColorBySpectra, color data can be obtained from spectral data obtained with any simple spectrophotometer, instead of requiring the use of a specialized instrument.
  • Color settings supported: Obtain color data in different color systems, CIELAB (L*, a*, b*, or L*, c*, h), HunterLab (L, a, b, or L, c, h) and CIE tristimulus XYZ. Choose among popular illuminants: noon daylight (D65), incandescent lighting (A), and cool white fluorescence (F2).
  • Flexibility: Instead of running a single sample at a time, an automated instrument such as a plate reader can be used, with bulk data converted to color in just a few clicks. With ColorBySpectra, users have the option to use dynamic sample volumes, and varying wavelength ranges and intervals (1, 2, 5 or 10nm). Small wavelength intervals provide more accurate color data.
  • Requirements: Java 8 or higher.
  • How to cite the use of the software: Farr, J. & Giusti, M. M. 2017. ColorBySpectra: an application to automate conversion of spectral data to color spaces. Software developed at the Giusti Phytochemicals Laboratory, Food Science and Technology Department, The Ohio State University.
