Should I assume this color change on the passenger headlight means the bulb is about to die-skies? The pic doesn't show it but it looks very violet colored.
I ran all different type of bulb in my old Clubman, and the best output were from high quality OEM spec bulbs. The ones on RockAuto are likely counterfeit China bulbs. The cheap bulbs will have good alignment inside the projector, and will not have great output. If you do any kind of night driving, you'll notice it right away. Buy from a reputable source, not RockAuto or Amazon, unless you really don't care.
Last time I check Rock Auto didn't sell anything counterfeit. That would be a reputational disaster for them. They do sell lots of crappy stuff and OEM manufacturer stuff but not counterfeit.
Where did you get his info?
The link to the brand u posted is the same price as FCP Euro and ECS which sell Sylvania OSRAM.

Could be a bad bulb or excess resistance either in the power side or ground side of the right circuit. For example, is voltage at the right passenger connector lower than at the left driver connector under load? Your LoadPro tester would be useful for this potential issue.
Another afterthought idea would be to swap the bulbs to see if the color differences follow each bulb.

I just did the Xenon to LED Ziza bulb/ignitor only upgrade on my Rover with factory xenon and its night and day on output going to led. Took a whole 10 mins to change them out.
Im completely uninterested in LED retrofit bulbs. Those housings were developed with XENON's in mind and just because something is LED doesn't mean its brighter, better, or will last as long.
The flap for the Bi -xenon has the correct cut off and will not blind/glare, its when you put LED with no cutoff in a halogen headlight reflector with non focused light - then your lifted truck LED type blind. I would not do that. ON the MINIs and Rovers you are fine as they are designed to take the fixed LEDs we have. They have a focused pattern with cutoff and the lens that's focused.
Xenons are good for a while until they get the pink death.
Thats pretty good! My factory xenons R58 lasted lit 7-8 years. On the R52 with the d2S they lasted 5 years, the actual end of the bulb were the small wire meets the tiny filament on top of the Xenon gas tube failed and it was OSRAM factory. They get brittle with heat cycles and the ride on the R53/R52/R50 have a much tighter suspension and seems to break those bulbs over time. Maybe a combined factor.
What most people fail to accept is that HID bulbs do have a life span. As they age, they get dimmer. Even though they light up, they lose brightness slowly over time. Most people think “they are light up, still good!” HID bulbs should actually be replaced every 5 years to maintain brightness.
