How do I know what color headlights I have?

This morning my driver side HID just gave out on my '04 TL. Because this car had many previous owners, I have to do the BULB or BALLAST test to figure out which to buy and change out. Luckily, I know how to do this fix from these forums :).

If it is the bulb:
I would have to buy a new one that matches the same color as the working one. The problem is, I have no idea what color my working bulb is. Maybe a previous owner changed them out? I know the stock Acura color is 4300k, but idk if that's what I got.

Any ideas how to check?
I posted some images below. Can anyone definitely tell what color this is?

Any help would be greatly appreciated!!
