Wavelength to RGB coversion

[G. Esteban Fernandez]

I have 4D (xyz + lambda/spectral) stacks from a Zeiss 710 confocal that I
need to render in 3D, with the lambda dimension pseudocolored in RGB.
Zeiss AIM/LSM and ZEN software do not render 3D volumes of lambda-colored
z-stacks or even export series of lambda-colored planes to TIFF (I'd have to
do 'em one by one) so I'm going to color each channel according to
wavelength using ImageJ's Image5D format.  Might there be an ImageJ plugin
or other software that reads the metadata and does this automatically?

Thanks,
Esteban
