Last night, Comicbook.com reported on how the Infinity Stone in a birthday gift from Marvel to director James Gunn was red instead of purple like it was in Guardians of the Galaxy. Gunn had previously stated that the Infinity Stone in Guardians of the Galaxy was a Power Stone (Gem), which is normally colored red in the comic books.
Well, it turns out that there is a rather simple explanation behind the color change. In a response this morning to fans asking about the color change of the Power Stone in Guardians of the Galaxy on Facebook, Gunn responded, “The power stone is purple because the aether already took red. And it's a better color for GotG.”
It has been previously revealed by Marvel executives that the Infinity Stones might not sync up exactly with the comic book counterparts, but it does appear that Marvel will not duplicate colors in their films. So since Thor: The Dark World used red for their Aether, it was unavailable for Guardians of the Galaxy. And even if it had been available, it sounds like Gunn liked purple better.
When Gunn had first revealed that the Infinity Stone in Guardians of the Galaxy was a Power Stone, there had been a lot of debate over if it really was a Power Stone, because of the purple color. Gunn’s latest answer puts to rest any question over if it really was a Power Stone in Guardians of the Galaxy. It was a Power Stone, it’s just one that was colored purple. And apparently, when Marvel put together their gift for Gunn, they just went back to the classic comic book red color.
