1. A color sensing system comprising:

  • a color sensing device further comprisinga housing having an external perimeter and a face,a controlled light source residing within the housing and offset from the face to define an interior within the perimeter of the housing, the face configured to engage a target surface about the perimeter of the housing wherein ambient light is substantially restricted from entering the interior, anda color sensor arranged to receive light radiated by the controlled light source and reflected from the target surface when the face of the color sensing device engages the target surface, the sensor further effective to generate output signals representative of a color of the target surface;

    a computing device having a display unit and a processor configured togenerate a user interface via the display unit enabling a user to select one or more of a plurality of available lighting conditions for the color sensing device, and to select one or more of a plurality of colors stored in a database, andgenerate, on the display unit of the computing device, a first image comprising the color represented by the output signals from the color sensing device, at least a second image comprising the selected one or more colors alongside the first image, and data corresponding to a difference between the first image and the at least second image according to one or more color models,wherein the color represented by the output signals from the color sensing device and the selected one or more colors are displayed in accordance with the one or more selected lighting conditions.
