ColorSynergy has a tool to create the optimal custom working space profile,
that just barely contains any set of colors. The color set may be
constructed from any combinations of instrument measurements, color
palettes, profiles, IT8 reference files, etc. This tool also has the
ability to compare your color set against any standard working space
profile, so you can see, in 3D, which colors fall outside the range of any
existing working space.
