I want to know the answer to the following question:
For what purpose were RLVs popular?
All the background I'm provided with is that "The only cosmetic difference between an RLV disc and a regular factory-pressed LaserDiscs is their reflective purple-violet (or blue with some RLV discs) color resulting from the dye embedded in the reflective layer of the disc to make it recordable, as opposed to the silver mirror appearance of regular LDs.". Is that enough to answer the question?
Answer: no
