opaque-not transparent or translucent; impenetrable to light; not allowing light to pass through. transparent-having the property of transmitting rays of light through its substance so that bodies situated beyond or behind can be distinctly seen. translucent materials-Translucent materials offer a signifi cant color measurement challenge since they interact with light in far less controlled manner than most other materials. The color of a material is calculated from measurements of its relative spectral refl ectance or transmittance. When light is incident on an opaque non-metal or metal surface, the fi rst surface interaction determines the corresponding perception of gloss and color. Similarly, for transparent materials, light refl ected at the fi rst surface is responsible for the perception of gloss, while light transmitted straight through the material gives the color. Translucent materials have both opaque and transparent characteristics. Some incident light refl ects off the fi rst surface as gloss, while some enters the material and undergoes multiple scattering and light trapping within the material, resulting in a diffuse pattern of refl ectance. In a second interaction, light is scattered and transmitted through the sample, emerging on the other side in a diffuse pattern. As a result, color can be seen in both diffuse refl ectance and transmittance, depending on how the sample is viewed. opaque example-books,stone,shoes,wood,stem of a plant transparent example-diamond , Pure Water , Screen , Air , translucent materials -waterbottles, eyeglass lenses
