Fluorescent colors are not lightfast. The inherent
nature of these colors that, as they "fluoresce," they expend their
potential energy and
will eventually deplete themselves. How long this takes is uncertain
and highly dependent
on a painting's incident light conditions. There are several
interesting articles on the conservation
of these pigments. Feel free to contact us if you are interested in
more information.
Fluorescent Colors are bound in alkali refined linseed oil.
