Yeah, I'm not a fan of the red-green combo, either. I don't think the colors go well, but on top of that, red-green borders are harshed by diffraction for anyone who wears glasses.
If you have glasses, and look at the chip on screen while turning your head left and right, you'll see the word "FIVE" move left and right, overlapping the green background. Red and green are near opposite ends of the color spectrum, so they don't get bent to the same degree when light is going through glass at an angle. (It's even worse with red/blue...)
