I took a series of photos to show the colour difference of the headlights, foglights, and Daytime running lights.
The headlights are the HID type
The highbeams are stock
The foglights are Eurolite Xenon Fusion - quite inexpensive, blue tinted

The daytime running lights look quite yellow compared with the other bulbs, they run about 50% voltage, so probably even aftermarket white-type bulbs will still look yellow.
I have disconnected my daytime running lights, and run the foglights on manual during the day (picture #3)
