Guy and Keith,
I am always looking for a better way to do anything. Like you, I am interested, but the link doesn't give us much to go on...There has to be a program that can not only catalogue with pictures, but also help us manage our mixes for certain colors...seems that there has to be something out there that can meet our needs...
Interesting though, but need more to go on...I'll share whatever I find.
All the best
Patrick
