holy beautiful jawn
From what I can see it has more of a blue purplish hue to it, instead of a FULL rainbow.
​
Similar to those old transparent purplish cases. [GBA] >

Yeah it is blue/purple more so than rainbow.  Rainbow isn't the best description.  I wasn't sure what to call it. >

Iridescent or Vapor wave >

Oh I like iridescent!  I might call it that. >

The name for the GB/GBA's color is Atomic Purple.
Maybe make a similar sounding name?
​
maybe something like Quantum Purple >

Quantum purple sounds legit.  I like it >

Doesn’t matter blue / purple or rainbow. Shut up and take my money.
