The Interface Innovations ColorTools toolkit calculates photometric quantities from spectral power distributions (SPDs) for inline instrument output or stand-alone applications.

Its industry-proven spectral analyses include CIEXYZ, CIEUVW, CIELAB, CIELUV, CRI, CQS 7.5 and 9.0, and luminous efficacy. Applications include a unit test framework to verify CCT, CRI, and dUV metrics with a NIST set of standard illuminants and sample industry spectra.

ColorTools includes the ColorCreator, a full-featured spectral composition and analysis tool that harnesses the toolkit. Packaged with a library of standard illuminants, stock spectra, and industry standards, ColorCreator offers standard spectral shapes to design theoretical spectra and determine the effects on calculated photometric quantities and rendering.

ColorTools also includes bin and ellipse test functions and examples for test data analysis; Graham scan construction of convex hull and smallest ellipse algorithms to estimate the data spread for the dUV analysis of measured data; a library of geometric functions used in the algorithms; and plotting functions for isotherms, bins, MacAdam ellipses, and all major plot types.

ColorCreator calculates photometric quantities from an SPD. See the Examples folder for usage. Commented block diagrams and comprehensive help are included.
