This isn't the issue. The issue is directing tiffgamut to produce a gamut
file in the colorspace that will be needed by icclink. Since icclink
can't be run until after the gamut is produced, it's up to the user
to anticipate what is going to happen. A warning is given
as soon as the problem is recognized - during icclink.
There are other solutions to this quandary, but they add complexity
and/or behave in subtly different ways. For instance, if icclink
created the gamut, then it would know what colorspace was needed,
but this reduces flexibility in creating the gamut. Using separate
tools allows for several different sources for the gamut, allows
averaging, selecting, viewing etc.
icclink could convert the gamut from D50Lab to what it wants, but
the gamut will be slightly different to one created directly in the
target colorspace, and I simply haven't got around to trying this
approach given that it's been a little used feature...
