Claim 13:
14. A color measurement device, the color measurement device comprising:
an integrating sphere having a specular port, at least one color measurement sensor and an illuminator;
a processor configured by code executing therein to:
cause the illuminator to illuminate the interior of the integrating sphere,
receive at least one color measurement value generated by the at least one color measurement sensor when a sample is present in a sample port of the integrating sphere and the illuminator is configured to illuminate the integrating sphere;
obtain a reference measurement value;
obtain a wavelength dependent calibration factor;
calculate at least a corrected measurement value for the color measurement based on at least the calibration factor, reference measurement value and the color measurement value; and
output, using the at least one processor, the corrected measurement value to at least one display device or data storage device.
