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.
From my fine art days - nothing was more costly than the precious natural cerulean blue (light sky blue), the more intense natural blue reds and certain brilliant greens - all those natural mineral source pigments are drastically precious, especially since artificial pigments just don't compare in brilliance, even using modern tech. Not hard to stretch them with all sorts of binders, but past a certain point, you just can't extend them without coming up with new ways of milling them down first.
Lightscapade certainly screams "expensive blue pigments" and I'm not surprised if it got watered down. This happens with other products like fabric in vibrant scarlet, emerald green, royal purple and cobalt blue too - synthetic dye just doesn't compare, even today, though it's getting better all the time.
I'd say it's a calculated risk to re-release a product under the same name but with a different formula - the trade-off between giving customers something they've been clamoring for and disappointing them after the fact with the 'ole bait 'n switch. Call me cynical, but I bet they still make more money bringing back an old favorite with a less than exact formula than introducing a new product with a new name. Business is all about the cha-ching.
