1. A method for formulating or rendering of a surface, comprising:

  • illuminating the surface with a first light source incident on the surface from a first illumination direction at a plurality of wavelengths;

    measuring reflected light at the plurality of wavelengths in a plurality of reflectance directions, wherein the plurality of reflectance directions includes at least a first reflectance direction, a second reflectance direction and a third reflectance direction;

    calculating an xDNA for the surface based on the measured reflected light, wherein the xDNA defines a weighted directional response of the surface that includes a set of vectors, and wherein each vector of the set of vectors represents a vector sum of light measured over all of the plurality of reflectance directions at a given wavelength or wavelength range; and

    using the xDNA to generate a color formulation or to render the surface on a display device.
