Hi, I'm Brazilian and I'm using google translate to translate to English and there may be some spelling mistakes, but going to the subject, my last blackcore racer keyboard has a problem, some leds do not fit the color I chose, example, I put red on the "2" key and it turns light blue, my cousin was with the same error, but he used an application that the keyboard solved this bug that I quoted and I was normal, I wanted to know what this application he said! (he said he found this app on the Razer website!)
