Abstract
An apparatus for determining a colour of a translucent material. The apparatus comprises a first light source configured to illuminate a translucent material at a first surface location, a second light source configured to illuminate the translucent material at a second surface location spaced apart from said first surface location, and a light spectral sensor configured to detect light at said first surface location. The apparatus is configured to operate the first and second light sources alternately, and such that light detected by the light spectral sensor originating from said first source is principally light diffusely reflected from said first surface location, whilst light detected by the detector originating from said second source is principally light scattered by scattering centres in the interior of the translucent material.
