Abstract

A method and apparatus for selecting wearables, such as cosmetics and clothing accessories, which match an object of interest, includes control logic for selecting an appropriate wearable based on a metric determined by light reflected from the object. Light is transmitted by an input device which also detects the reflected light. The input device is connected to the control logic which determines a metric and compares the metric to predetermined data corresponding to each of the available wearables. The selected wearable is indicated to a customer by an output device also connected to the control logic. The output device may include a light corresponding to each available wearable, or a mechanical machine which provides the selected wearable or a sample of the selected wearable to the customer. In one embodiment the apparatus is utilized to match the color of a cosmetic foundation make-up to the color of the customer'"'"'s skin.
