Use this tool if you have Lab color coordinates as Aims.

This is a very simple tool but take into account that L*a*b* coordinates require proper Color Specification.

The most important Color Specifications are:

• Illuminant - which in Print Industry is typically D50 in Color Manufacturing ( plastics, paints, textile) D65 but might be different including custom.
• Observer - 2°  (print) or 10° (paints, automotive, ...)
• Measurement Condition (that typically specifies the amount of UV component ( M0, M1, M2, ...) 
• and Geometry setting (angles, aperture, SPIN/SPEX...)

Be sure that Instrument Color Specification match L*a*b* coordinates specification. The potential error might be huge.

Lab coordinates used by Chromachecker are CIELab, not a Hunter Lab.
