How many different colors are in the Pantone “Bridge” color guide?
Using Four-color Process (CMYK), the number of possible color combinations are vast. I wouldn’t know how to calculate the many variations that are possible. The Bridge is a list of PMS colors (Pantone Matching System) with a corresponding formula for creating similar colors using 4 color process. Even if it were possible to chart all of them, I suspect that there are variations of this color guide so the number would vary with each version printed.
