For those not in the know, this is Rainbow Raider.
He’s a super-villain of DC comics, he was born colourblind, but not the way colourblindness works in reality, he literally perceived the world in monochrome.
He wanted to be an artist, but due to his inability to use colour well he failed his classes, his father invented for him some goggles, that would supposedly allow him to see colours.
They actually just allowed him to shoot colours out of his eyeballs and generally manipulate light without fixing the colourblindness at all.
Since he cannot create his own beauty, he has resolved to steal beauty from the rest of the world. Mostly this just means stealing famous paintings though.
And if you’re familiar with DC comics and the way the minds of their writers work, especially the writers of Batman, you’ve probably already guessed his given name is Roy G. Biv.
Round of applause for Rainbow Raider everybody.
