ARTS & SCIENCES
Colours change depending upon the hour of the day, the type of artificial light in rooms, reflection of neighbouring objects, preconceived ideas, one's visual capabilities, one's mood, etc. (People who study polished sections in reflected light, with a metallographic microscope, do well know how to take these problems into account!).
Several pictures were taken in poor conditions: with insufficient light or without a tripod. Moreover colours change when the pictures are developed, scanned, displayed or printed.
For these reasons, pictures displayed on this site must not be considered and copied as reference documents. They must be considered as an incentive to establish links between fields of knowledge.
