The existing recolor skins should be re-released as part of a Chroma pack (priced at 590)
Summoners who own any of the contained skins will receive the Chroma pack for free.
Legacy Chromas would be treated as Legacy skins and would only be periodically available.
Vintage Chromas would be treated as Traditional skins and, while officially classified as Legacy, would only be scarcely available. Existing owners would receive Vintage Artwork and the Vintage Icon, while new owners would use the base skin's artwork.
If possible, skin artworks would be applied when the specific Chroma is chosen. The name and a watermark should denote that it's a Chroma.
Premium Chroma Packs can feature new animations, voice filter or changes to non-champion models (e.g. Trundle'sPillar or Zac'sBloblets) but still use an existing skin as a base. These would cost 750 and would ideally have their own loading artwork.
For me, the names should refer to a theme rather than being a unique identifier - this is primarily (no pun intended) because "Prime" brought to mind "Primary" (i.e. primary colors) and my brain has been stuck on that association ever since (as opposed to "Prime" being an adjective to symbolize importance). Summoners should be able to search "Prime" to get a list of all the Primary Color skins.
Some packs, such as Condiments Zac, would still be skin-specific.
