Adjusted color prescriptions for aqueous coating compositions to correct gloss differences

A process for correcting an observed color difference between a color at a first gloss and the color at a second gloss different than the first gloss, said process comprising the steps of:

• (a) determining a whiteness correction caused by a lightness (Y-value) of the color at the first gloss;
• (b) determining a non-directional reflection correction caused by an inclusion of a first surface diffusion in readings of gloss values;
• (c) determining a specular correction caused by a difference in specular reflections from the color at the first gloss and the color at the second gloss based on the whiteness and the non-directional reflection corrections;
• (d) determining tristimulus or spectral correction based on the specular correction;
• (e) preparing corrected tristimulus values of the color at a second gloss based on step (d);
• and
• (f) producing a paint composition for the color at the second gloss using the corrected tristimulus values, or a color merchandise for the color at the second gloss using the corrected tristimulus values.
