A look back at all the comic book references and Easter eggs from last night's episode.

Welcome to Flash Facts, a new weekly column dedicated to discussing the various comic book references, Easter Eggs and other cool facts about The Flash, CW's new superhero show. While I'll attempt to be as thorough as possible, I'll definitely miss a reference here and there. If I miss something, feel free to comment or shoot me a Tweet at @OH_IGW, and I'll gladly add it in and credit you. If you enjoy this column, be sure to check out Arrow Annotations, which discusses similar references over on Arrow.

Palmer Technologies - In the opening sequence, Barry paints a building that's being improved thanks to Palmer Technologies. Palmer Technologies is the company of Ray Palmer, aka the DC superhero Atom. Palmer is currently appearing as a supporting cast member over on Arrow.

Gold City Bank - Poor Gold City Bank. The Central City financial institution was previously robbed by Clyde Mardon in the pilot episode of The Flash.

Cunningham and Sampere. - Gold City Bank is located on the corner of Cunningham and Sampere. Brian Cunningham is the current editor of DC's Green Arrow series, and Daniel Sampere is the book's penciller. Green Arrow is currently written by Flash producer Andrew Kreisberg and Arrow writer Ben Sokolowski.

Rainbow Raider - Roy G. Bivolo is a minor villain of the Flash better known as Rainbow Raider. In the comics, Bivolo was a colorblind artist who was given a pair of special goggles by his dying opthomologist father. While the goggles were intended to cure his color-blindness, they instead gave Bivolo the ability to project rainbow color beams of hard light, and to manipulate others' emotions by projecting certain colors of light onto them. Bivolo quickly decided to use the googles to steal famous pieces of artwork, which brought him into conflict with the Flash.

The Rainbow Raider became a recurring villain of the Flash. During the events of Flash: Iron Heights, Bivolo joined a new team of Rogues (the same team which included Girder), but was killed by the Rogues' leader Blacksmith. A team of villains later decided to call themselves the Rainbow Raiders in his honor.

In the New 52, Rainbow Raider (calling himself Chroma now) made a brief appearance when he tried to ally himself with Grodd and his gorilla army. Grodd declined the offer and decapitated Chroma instead.

Rainbow Raider was created by Cary Bates and Don Heck.

Boomerang - The Arrow team came to Central City to investigate a death by boomerang. In the last episode of Arrow, we saw Flash villain Captain Boomerang make his first appearance on the show. He'll be the main villain of the second part of the crossover, and will be discussed further in this week's Arrow Annotations.

Singh's Boyfriend - Captain Singh references his health-conscious boyfriend while talking to Joe and Eddie this episode. In the comics, Singh was involved with Pied Piper, a foe turned friend of the Flash. Pied Piper will be appearing in a later episode of the show, so we'll talk more about him then.

Emotional Spectrum - Caitlin and Felicity briefly discuss the concept that changes in the color spectrum can affect emotion. Geoff Johns' Green Lantern series introduced the concept of the emotional spectrum of color to the DC Universe and tied each of the seven colors of the rainbow to a different emotion. Red was associated with rage, which matches the red tinge shown in the eyes of those affected by Bivolo's powers this episode.

Dr. Wells later uses blue, purple, pink and green lights to calm Barry down. Those colors are tied to hope, compassion, love and willpower in the emotional spectrum.

Sandra - Last season, a late episode of Arrow (coincidentally named "Seeing Red") revealed that Ollie had impregnated a young woman during one of his many trysts behind Laurel's back before he was stranded on Lian Yu. Ollie's mother, Moira, paid the woman off to hide the pregnancy from Oliver, and she moved to Central City.

That woman makes a brief appearance at the end of the episode, running into Oliver at Jitters. IMDB lists the character's name as Sandra (which is the name of the mother of Conner Hawke, the second Green Arrow and Oliver's son), but I'm trying to hunt down some sort of second source confirming that characters name.

Firestorm - Hey, it looks like that Ronnie Raymond fellow has fire powers of some sort!

Manchester Black - The thug who confronts Ronnie at the end of the episode has an outfit remarkably similar to Manchester Black, a DC antihero and foe of Superman. Manchester Black usually wore a long trenchcoat, boots and a shirt with the Union Jack (the flag of the United Kingdom) on it. It might be a coincidence, or it could be a little Easter egg. I'm not quite sure yet.

And that's it for this week. Be sure to read Arrow Annotations tomorrow!
