Abstract: A system and method of characterizing a color variation of a surface includes a device having a light source and a plurality of sensors positioned at respective viewing angles. An algorithm is stored on and executable by a controller to cause the controller to direct a beam of light at the measurement location with the light source and measure the light leaving the measurement location with the sensors at a plurality of azimuth angles to obtain respective measured color values. The controller is configured to define a color vector function F(θ, φ) to represent the color variation of the surface. The controller is configured to determine the color vector function F(θ, φ) based at least partially on the respective measured color values. The system allows for a representation of color space of a surface at any azimuth and viewing angle.
