You may or may not be aware of the
Razer Chroma Workshop. This is a piece of software that games developers are able to use to tap into the lighting that Razer controls. For instance, when I'm playing Orcs Must Die, I can have my RGB lighting signify me of upcoming events, the angle of attacl, or even start pulsating an entirely different colour when my "special attack" is ready.
I currently have the Razer Nommo Chroma speakers, Razer Tiamat RGB headset, Razer Mamba Hyperflux + Firefly, Razer Blackwidow Chroma V2 and the Razer Chroma Hardware Development Kit, all of which adds up to give me an
EPIC experience when I play supporting games.
So RGB
can, on occasion, be used to actually give me an advantage.
