The aim of this project was to observe the effect of shooting in fluro lighting, and to use colour balance (in the case of digital shotting) to remove the various colour casts that fluros give off. I took photos in 4 different interiors; a supermarket, home, shop and art gallery. In each of the photos I think the best (closest to reality) WB setting is Auto WB. I feel like both the Sunny WB and the Fluro WB at times give an unpleasant colour cast. I think the lesson with this project is to use Auto WB when shooting inside unless there is a lot of natural light around, or some test shots can be done with different settings at the start of the shoot. I have had problems before with using Auto WB if the photos are to be used as part of a set, and the colour cast changes throughout the set. This could perhaps be overcome by setting the WB manually (which I have not tried) or using the RAW files and manually setting WB that way (which I also don't often do).
Apparently the variations in colour cast are due to factors like the make of the lamp and that they can change colour with age. The only sure way to know how to set the WB is to do test shots or edit the RAW file later.
The four interiors are shown below, each set of photos with 3 different white balance settings:
