A site dedicated to the Management of Light and Color in Lighting Design and Digital Color Applications. Here, you can find prerelease versions of the books I am writing. It is also home to the CIE-JS WebAssembly Library, implementing colorimetric algorithms for Colorimetry and digital color management applications. Lastly, find here a collection of easy-to-use, hands-on online Vision Tests and Color Calculation Tools.

Correlated Color Temperature & Tint Calculator

The color of "white" light is typically expressed using a correlated color temperature and a Tint value and can be calculated using this tool from a range of input parameters such as x and y chromaticity coordinates and X, Y, and Z tri-stimulus values. Accurately calculating correlated temperatures is hard. This easy-to-use tool uses a high-accuracy bisectional search method, which builds upon an algorithm [...]
