One idea that Gracie came up with and we may go for is to mimic the duality of pokemon generation games.
So for example, in Pokemon Red and Blue, there are certain pokemon that only appear in one version - like Weedle for Red, Caterpie for Blue.
If implemented, we'd randomly assign a type/affinity/version for each trainer and for all new trainers to a particular version, and then there are specific pokemon which that particular trainer cannot encounter - probably based on the real games' unique lists. These would only be obtainable for that user through trading.
Since RMRK has had a heavy association / affair with purple for many years, we think shades of purple would be good to go with. So pick two above.
The colours and names are ripped from wikipedia's shades of purple, though if two similar shades win we can switch one out. I guess this means, choose more based on the name. For the first day or two of the poll, if any nice names are suggested I could add them.
