M4 Headlights colour?

[BmwFan91]

Just a question..

Looking to buy an M4 and I've noticed quite a few of them have a range of colours in terms of headlights. (Colour of the light projected). I've attached a few examples below. Is this just the lighting and camera used or is there actually a difference is spec? Many thanks!

the SNL plate ones look like LEDs and the others are xenon

Upper one looks like a pre-face-lift xenon, can't tell, what's the year of the car?
Middle one 17 plate is base LED face-lift
Bottom one 14 plate is base xenon pre-face-lift

You can't rely on pictures for light color. All modern cameras have a adjustable color temperature settings called white balance. Photographers understand this.

If you want to dig deeper, look up color temperature and white balance on Google.

Fun note, if you wear polarized glasses, the DRLs look kinda greenish.

Exaggerated example. Same photo, different white balance.

There is definitely some variance when it comes to DRL colors. Ive had headlights where one looked more blue and the other looked more green/yellow
