It's difficult, that's why Pantone charges thousands of dollars. You know those chameleon car paints that change color based on sunlight or angle? Turns out everything is like that somewhat. You can have two parts match perfectly under a fluorescent light and then look like totally different colors under sunlight. I had to come up with a color scheme for a factory where all the colors matched, but all the different machines used powder coat, wet paint, polyurethane dip, all sorts of things. In the end, how we had to do it was buy a very expensive Pantone physical set of chips and light boxes, which costs thousands of dollars each and physically give these to all of the suppliers to match. We had to include this light box contraption with various bulbs and angles and a camera. You could define the spec by Pantone's written list, but you can't ever meet the spec without Pantone shipping you this science fair project.
