Is there a tool in argyll to create standard colorspaces? I'm interested in creating a Public domain ProPhoto (and several other spaces). I'm assuming I can take the values from http://www.scarse.org/goodies/profiles/ and generate a profile and put it into the public domain. I'm pretty sure I could create a profile using lcms and a bit of C, although I wondered if there was a better way to do this. Thanks. Richard.
