Light output color:
1) 3200K ~ 3800K = stock. def yellowish. No doubt about it.
2) 4100K ~ 4250K = pure white range.
3) 4300K ~ 4500K = slightly bluish white. (Factory HID range.)
4) 4500K ~ 5000K = blue white.
5) 5000K ~ 6000K = blue.
Filament glass tube color: (In general.)
1) Clear.
2) Slightly colored, yet the reflection on the housing is barely noticeable.
3) Pretty blue. Noticable.
4) Very blue. Housings become blue.
5) You would know how it goes.
With that said, if you get the one from that link, you are going to get 1) on the list above. Btw, the package says 3100K but the description says 3800K lol.
The glass tube color really depends on its brands (technologies) but, if I were you, I'd look for 4200K for the purest white, and decide which brand has the least color of its filament glass tube. ← (Assuming that you like having white output color by saying "white 5000K".) If not, the link you provided would do the job, since the glass tube is clear. But the light output will be like stock beam.
Here are my past (4100K), previous (4250K), and current (4500K) halogens from PIAA:

(Don't have a pic of the light output on 4100K's but it was pure white from a distance yet very tiny hint of yellow at close range.)
(Pic of my current 4500K output is bluer than the reality, since I edited the pic for color balancing to get the SSM more realistic.)
