Wherever the color plays a key role, an objective method is needed to determine the color of a product consistently. Whether in product development, during the manufacturing process, but also across companies between suppliers and customers...

At first the spectral reflectance of the sample is determined with a spectrophotometer. From these reflectance values, the CIE tristimulus values X, Y and Z can be calculated, as well as the color coordinates for the Lab and the LCh color space.

The calculation is based on either the 2° or 10° standard observer and can be started for different illuminants.

You can enter the reflectance values in the following ways:
