Methods and apparatus for measuring an electromagnetic radiation response property associated with a substrate and selecting a color for use by a personal care product recommendation system based on the measurement are disclosed. The method positions an electromagnetic source, an electromagnetic capture device, and a plurality of filters in a predetermined arrangement in order to construct an apparatus for measuring an electromagnetic radiation response property associated with a substrate. A retail customer self-aligns a portion of his/her body with the apparatus and triggers an electromagnetic measurement. Digital data is determined from captured electromagnetic waves. Based on the digital data, the customer is given certain choices and/or informed of certain personal care product recommendations.
