Hi Robert,
Somehow, you should set fi.reds, fi.greens and fi.blues of your FileInfo
object and then create and set a ColorModel as seen at:
https://github.com/imagej/imagej1/blob/master/ij/plugin/LutLoader.java#L90If you look at further in this class, you'll find various methods to set
r,g,b arrays from different sources (create from scratch, or load from
binary or text file).
Jerome.
