For purple I read Chain Mail Bikini edited by Hazel Newlevant. It’s an anthology about female gamers. I got it at a local SPX and got several of the contributors to sign it. The cover is also purple and red so I thought it cycled nicely back into the beginning of the rainbow.
The stories vary from silly recollections of playing video games growing up to the bigotry in LARPing groups and how that’s changed over time. Because the stories are so different, it kind of gave me whiplash to read too many at once. The representation was great from trans people to gender queer and the exclusion and inclusion they all faced. I recommend it. 4/5
