   Whichever scanner you use, it makes a lot of difference if you can use a
good quality monitor and colour matching lighting in neutral coloured
surroundings. Some of the older television tubes used very expensive
rare-earth phosphors to give the correct colour response, especially an
extended red rather than an orange-red. Cheaper screens are unlikely to give
the correct answer.
   Another problem is due to the ordinary flourescent lighting tubes. The
eye can tolerate a lot, but if you look carefully their colour is often
strange, and photos taken with a mixture of lighting often show flourescents
as a strange pink colour.
   A very useful facility used in television colour matching is a push
button which instantly swaps between the full colour RGB drives and
identical monochrome drives, allowing persistence of vision to accentuate
any colour errors despite a less than perfect monitor.
