While I was a graduate student in mathematics, I also worked as a consultant for Deering Milliken Research Corp.  One of the projects involved investigating a computer program that selected dyes to use in dyeing fabric to match a given color.  There are several components to the basic problem, including the fact that dyes produce different colors on different fabrics; however, the central problem is that the human eye does not react to color in exactly the same way as do the machines that measure color.  To make a good color match, you want to select dyes that produce a visual match, not a machine match.  The existing program did just that.  However, there were questions concerning the topological transformation between the machine color measurment space and the human visual space.  I confirmed the validity of the transformation and adjusted the computer program to use a better metric in choosing alternative dye sets.
