Systems, methods, and interfaces for comparing complex coating mixtures with sparkle color

A computerized method for use on a computer system comprising one or more processors and one or more computer-readable media having stored thereon executable instructions that when executed by the one or more processors configure the computer system to perform a method of comparing complex coating mixtures with sparkle color, the method comprising:

• receiving at least one image of a target coating;
• calculating a sparkle color distribution of the at least one image of the target coating, wherein the sparkle color distribution represents a relative number of sparkle points of one color compared to a number of sparkle points of one or more other colors in a measured area;
• searching a database for a plurality of reference coatings with sparkle color distributions that match the sparkle color distribution of the target coating, wherein each reference coating in the plurality of reference coatings has a different sparkle color distribution;
• calculating a degree to which the plurality of reference coatings matches the target coating based on sparkle color distribution;
• and
• generating a list of closest matching sparkle color distributions for the plurality of reference coatings compared to the sparkle color distribution of the target coating.

• receiving at least one image of a target coating comprising RGB values from pixel image data;
• calculating a sparkle color distribution of the at least one image of the target coating, wherein the sparkle color distribution represents a relative number of sparkle points of one color compared to a number of sparkle points of one or more other colors in a measured area;
• searching a database for a plurality of reference coatings with sparkle color distributions that match the sparkle color distribution of the target coating;
• calculating using a z-score analysis a degree to which the plurality of reference coatings match the target coating based on sparkle color distribution;
• and
• generating a list of closest matching sparkle color distributions for the plurality of reference coatings compared to the sparkle color distribution of the target coating.
