The Chroma-enabled Razer peripherals will be available starting September 2014, while the Chroma SDK will be available in late 2014. “Chroma represents more than just multicolour, it opens up limitless personalisation options for gamers to play with and we even have a Chroma Software Developer Kit for game developers to integrate their games to provide even more customisation in the future.” “Our new range of peripherals that feature Chroma customisable backlighting is another step towards full personal customisation and to interconnect our gaming tech,” said Min-Liang Tan, Razer co-founder and CEO. Chroma modes include spectrum cycling, which cycles through the entire spectrum of colours breathing, which pulses in a colour of choice every seven seconds static, a colour that illuminates the ear cups on a Kraken 7.1, the scroll wheel and Razer logo on a DeathAdder or each individual key on the BlackWidow Ultimate Chroma reactive, which lights up upon actuation and stays lit in short, medium or fast mode for a trailing effect and wave, which animates all colours in a continuous wave of rainbow lights.
