This might be what you're seeing.

Not quite. Let me set the record straight on the bulbs.
1. Phillips and Osram are two different companies. Phillips bulbs last longer and do not color shift nearly as much as Osrams over time (look at an older Acura TL with 1 purple headlight if you want to see Osrams in action.
2. Phillips code for the D2S bulb is 85122 and 85122+. The 85122 is a normal 4300k HID bulb, while the 85122+ is brighter by a couple hundred lumens, and is closer to 4100k in color. If you compare the two, the 85122+ has a yellower light, but it is brighter, and at the end of its life cycle will only dim and not color shift.
3. The lights will shift in color after burning in (around 100 hours of usage), but not very much. 85122s settle in around around 4800-5000k, while the 85122+ was specifically designed NOT to colorshift.
4. Option 3, if you are matching another bulb, get the Phillips 85122CM. This Bulb is a 4800k bulb and is designed to match older 85122s.
If you got any other HID-related question, LMK.
