摘要： A color ruler for objectively measuring skin color and methods of using same. The color ruler has a scale with indicia of at least two different color attributes captured in a medium, the scale having been determined by the following steps: (i) Taking multiple photographs of multiple subjects; (ii) Sorting said photographs, thereby classifying them according to said color attributes to obtain sorted data; (iii) Analyzing said sorted data; (iv) Selecting at least one representative image; (v) Transforming the representative image to create equal intervals and remove imperfections; and (vi) Validating said color ruler by checking the correlation between the visual score given by use of the color ruler and the chromameter measurement. A cosmetic product system is also provided which includes a cosmetic composition for skin lightening and a color ruler device packaged with the composition. Also provided is a method for assessing skin color attributes on the color ruler scale, for evaluating progress of skin lightening occurring over a period of time within which the composition is applied to an area of skin being monitored, and for product selection guidance.
