<p>A method, apparatus and computer-readable medium allows users to measure a lighting condition of an object. In one embodiment, at least one user visually compares colored materials against a displayed color sample (33). Users may adjust the color of the displayed color sample by changing corresponding attribute values until the displayed color sample appears to substantially match the colored material (35). Once users indicate that they have established a color match between a displayed color sample and a color material, the spectral irradiance value of the substantially matched color sample is calculated (37). The spectral irradiance value represents a measurement of the lighting condition in a particular room.</p> |
