HG can certainly correct me if I'm wrong, but I suspect that the issue with certain items being cost-prohibitive to offer again might be especially relevant for products that contained a larger number of colours. More colours = more ingredients = more opportunities for prices to rise. In that case, I would think that Blonde and Redhead might be safer, because the tones involved are mostly variations on a couple of base pigments, rather than combinations of entirely different colours.
I think that PixieDancer nailed the issue exactly. Chances are that no one would have complained about the "Beigescapades" if they had just given them a different name. Everyone would have been happy to get something that was pretty close to the original Lightscapade. Using the same names invites the comparison and invites criticism that you messed up. Using a different name would allow people to enjoy the improved formula currently available.
