Physics Optics/Color

  • Absorption of Solar Energy by Different Colors - A simple experiment testing the effect color has on the absorption and reflection of solar energy.
  • Causes of color - Explore the phenonmena that create our colorful world.
  • Color FAQ - Clarifies aspects of colour specification and image coding that are important to computer graphics, image processing, video, and the transfer of digital images to print.
  • Color Matters - Several resources about color and its relationship with other human activities.
  • Colorworm Explains Color: A Free Book - Both a science and an art book, Colorworm explains the electromagnetic spectrum, visible light, how we see, mixing paint, RGB, and CMYK with library look-up and a storytime cut-out. Target audience is grades K-8.
  • Colour Info Page - A rapidly growing site covering many aspects of colour science.
  • Colour Physics FAQ - Concerns the measurement and control of coloured surfaces such as plastics, textiles, and surface coatings. It is intended for practitioners rather than theoreticians.
  • efg's Computer Lab: CIE Chromaticity Diagrams - Demonstrate how to display a 1931 CIE chromaticity chart, as well as the transformations needed for the 1960 and 1976 charts. The charts can be displayed using either the 1931 2-degree or 1964 10-degree standard observer.
  • efg's Computer Lab: Color Mix Lab Report - Interactive demonstration of mixing additive or subtractive colors.
  • efg's Computer Lab: Maxwell Triangle Lab Report - Demonstrate mixture of light with three primaries. Introduce concept of chromaticity coordinates.
  • efg's Computer Lab: Spectra Lab Report - A complete Delphi program, including source code, to display wavelength colors as a function of wavelength and optionally display the emission and absorption spectra of hydrogen.
  • Glossary of Color Science Terms - When one speaks about color, some of these terms are sure to be used.
  • International Commission on Illumination - Devoted to the normalization of several aspects of light and color.
  • Molecular Expressions: Science, Optics and You - An educational resource for the science of optics and the physics of light and color intended for teachers, students, and the general public.
  • Munsell Color Science Laboratory - Academic laboratory dedicated to research and education in color science, based at Rochester Institute of Technology.
  • Theory of Color - Unconventional way of classifying and teaching colors.
  • Whiteness - Explanation of applying fluorescent whitening agents to increase perceived whiteness.
