This will never replace eye observation, but this can be used before building the real models, in order to reduce their required number.

We propose in this post to use the OceanР Р†РІР‚С›РЎС› software for showing how physical image synthesis may be used for finding optimal color tolerances. In the example of car paints, this would imply building simplified (and eventually reduced-size) car models with many different paint variations, for severalР вЂ™Р’В Р С›РІР‚СњE values, and in several directions of the color space. The best method for choosing the optimal Р С›РІР‚СњE color difference is visual observation in real conditions, but this may be very expensive. However, this value may vary a lot depending on materials and lighting conditions.

Color standards such as CIE 1976, CIE 1994 and CIE 2000, which define color differences, suggest a value of Р С›РІР‚СњE=1.0 for the Just noticeable difference (JND). If they are too narrow, sustaining production with a high yield is not possible. The target is not only a single color value, it must provide tolerances for the color coordinates, in which the product can be considered as good.Р вЂќР’В¬hoosing optimal color tolerances is a difficult task : if they are too large, the product will have a poor visual quality. Some industrial processes produce variable colors, that are adjusted to match a given target.
