Abstract: The color strength of a colored batch containing effect pigments can be measured and corrected using one or more non-uniformly weighted factors to determine, at a plurality of combinations of illumination angles and measurement angles, and at one or more wavelengths, the color and intensity of light reflected or absorbed by a coating film made from the batch in comparison to a reference color strength. Based on such comparison, let-downs or batches may be passed, rejected, mixed or otherwise dispersed. The composition of such let-downs or batches may also or instead be adjusted by adding non-effect pigments, effect pigments, binder, carrier, binder, or non-effect or effect pigments dispersed in either or both of a carrier and binder, in order to correct the let-down or batch color strength to within a desired tolerance of the reference color strength.
