I9m happy to say my life as much simpler than that.
I do work with fluorescent colors. But in a picture I don9t care if the
colors are not really9 fluorescent. As long as they appear9 fluorescent.
It9s easy to make a color in a photo appear fluorescent: Open the file in
Photoshop, make a selection of a surface that is allready white (for
instance a white car) and make it lighter (the surface will hardly ever be
Lab 100-0-0). The surface will be whiter then white9 and thus, from a
perceptional point of view, fluorescent. No need for a "double gated-turbo
boosted-high end-spectro-with 12 valves per cylinder".
