Reflectance measurements The impression of brightness and colour of an object depends on the character of light illuminating the object, the reflectance and absorption properties of the object, and the relative sensitivity of the eye to different wavelengths of light. Giving the relative amount of radiation at each wavelength i.e., the spectral energy distribution of
