Abstract
A method includes determining a fielded color measurement instrument is not calibrated to measure light emitted by a fielded light emitting device, assembling a calibration matrix, such that a product of the calibration matrix multiplied by a response of the fielded color measurement instrument to the light emitted by the fielded light emitting device is a triplet that corresponds to a Commission Internationale de L'éclairage XYZ color space, wherein the calibration matrix contains measurements made by the fielded color measurement instrument of a first plurality of lights emitted by the fielded light emitting device and measurements made by a spectroradiometer of a second plurality of lights emitted by a reference light emitting device of a same make and model as the fielded light emitting device, wherein the spectroradiometer is located remotely from the fielded color measurement instrument, and storing the calibration matrix on the fielded color measurement instrument.
