The 10 pages that link to Color index, each with the reason it gives.

• Hertzsprung–Russell diagramRelated: Color indices can estimate temperature when a spectrum is unavailable.

• Interstellar extinctionRelated: Changes in color index reveal wavelength-dependent attenuation.

• PhotometryRelated: Differences between filtered measurements encode spectral shape and stellar temperature.

• Absolute magnitudeRelated: Band-specific absolute magnitudes can be compared to describe intrinsic color.

• DyeRelated: Its standardized entries distinguish dyes by chemical identity and application class.

• Sloan Digital Sky SurveyRelated: Colors from SDSS filter measurements help distinguish stars, galaxies, and quasars.

• Spectral energy distributionRelated: A color index samples the distribution at two wavelength ranges.

• Atmospheric extinctionRelated: Wavelength-dependent extinction changes measured colors as well as brightness.

• Astronomical filterRelated: Comparing filtered brightnesses produces colors used to infer astronomical properties.

• Visible-light astronomyRelated: Visible color indices estimate stellar temperatures and help distinguish interstellar reddening.
