LED color issues

I just got my galaxy s 3 yesterday (white colored) and while playing with it I noticed that my led lights are kinda weird. What is white and green color leds have a violet and orange bleed through in them respectively. I was under the impression that the color should be pure white or pure green. the only colors not having a problem is blue and red. Is this normal? Is anybody else experiencing this let me know.
