Bulb color and flicker are two different things actually, bulb color control light output in front of your car, flicker is created by the projector itself (mainly the lens).
That flicker effect is created by the thick color band at the projector cutoff, you are seeing the top color of the band if you are far away from the projector, as you get closer you are cutting into other color within the band and eventually you'll see just the white/yellow light. With 5000k PnP kit in my stock J-Spec, oncoming traffic will only see one color at any angle or distance because the lens doesn't create any color band at the cutoff. On the other hand, my TSX'ed J-Spec shows deep purple from beyond 100ft, then slowly turn into deep blue around 50ft, then light blue then bright white as I get closer to the observer.
J-Spec with 5000k PnP kit, no color band at cutoff.
E55'ed J-Spec , little blue band right at the slope.
TSX'ed J-Spec, color modded, lots of color across the cutoff.
SC430 with spaced E30 clear lens, these are going on the FD.
Some halogen projector is capable of creating color band at the cutoff, but mainly some newer OEM one like the Mazda3 and tC.
