I am a programmer with not much colour management background. Quite
happy to release any code I write if it is of use to anyone else.

I need to calibrate a computer controlled LED light so that people can
specify colours and get something close to what they want (what that is
is slightly unclear as they are basically print based people and really
want to specify Pantone, but sRGB will probably do as a start).

I have a Minolta colour meter that will measure Yxy (and is in theory
scriptable, though I dont yet know how much control you get from the
serial interface), so I should be able to get a mapping from 24 bit RGB
device space to Yxy  (possible complete if I can automate it and leave
it in a dark room for a long time).

How do I then go about converting this to an ICC table that I can use
with lcms? If I cant sample all colour values, how should I choose the
selected points?

Thanks very much for any help
