Titanium Gray S3 led problem

So I got rid of my white S3 was tired of that white look and the LED bleed on the keys n notifications so I got myself a gray an must say its kinda gorgeous but sum how the poor thing cant seem to produce anything but red, blue, green, a kind of a purple and a kind of a yellow...anyone else with the gray has this issue or any other color besides the white? I jus wanna knw cuz i really use light flow and now I get variants of blue -_- Oh n nw i hav the gray cases dont match so anyone with gray wat kinda case u have n colour? thanks much :)
