The blue / purple hue you have must be from the 6000K bulb not the projector (my 4300K's in projectors has little if any blue / purple hue)

Back on topic, providing the xenon's are OEM looking (colour wise) and have a nice non dazzling/scattering beam then they will not draw any unwanted attention come either MOT time or by the police / VOSA.

In my experience its only when things don't look right or are badly setup that anyone will be bothered to dig deeper (unless you have been stopped for driving like a complete idiot, then they will keep looking until they find something)

The halogens fitted to it previously did the same and a lot of projectors do it (The OEM Xenons in my Fabia did), the lense is separating those colours through dispersion and as a result it has a certain level of chromatic aberration. I bet if you could look at that outline a lot closer you would see a few other colours too.

Chromatic aberration - Wikipedia, the free encyclopedia

I don't know enough about it to work out the specifics, but in my house I tend to obey the laws of physics

Here is the bulb on it's own without a blue hue

I totally agree.

Its ironic but the biggest drawback with HID light is the poor quality of its light. If you take a top quality Philips halogen bulb at just under 80w it should give better visibility and reduced glare compared to there OE 35w HID bulbs do. But a 80w halogen bulb is not road legal. The people making the laws must have some really unusual logic at times.

i think its more to do with the fact 80w bulbs are not designed for car headlights as the heat they give off will just melt and deform the headlight.

I really don't agree with that. There is no glare with good HIDs and the light is clean and crisp. The throw is about the same as a normal 55w Halogen with the added advantage of lighting up reflective surfaces like roads lines/signs much further then standard incandesent bulbs. The OEM Xenons and the ones fitted to my Vroomster give a greatly increased field of perception despite the fact they probably have less luminous intensity.

You will probably get more candela out of an 80w halogen but it's probably too much to be useful and as mentioned will just melt the headlamp.
