Aside from the excellent info provided by Ilya, let me add this. You asked about bulbs that might look "ricey" which I assume means cheap, or funky? The color of your car has nothing to do with bulbs, so I don't get what you're on about there. The actual headlamps themselves are what gives a car a high-end look or a wanna-be look. As stated above, you want to stay between 4,500 and 6,000 kelvin for the color. These bulbs will look high-end and avoid the 'cheap auto parts look alike' colors.
The best bulb on the market (in my opinion) is the Osram 66240 Xenarc CBI (cool blue intense). I am on my second M and installed these bulbs on both cars. They provide an extremely wide beam and throw light farther ahead than most other brands. There is a night video in my sig taken with my old M driving in low lighted areas and also on the motorway to show the effects under different conditions. Give it a go and you will see the difference they make.
What Ilya was explaining in his reply DID answer your question and also provided a great explanation of why bulbs do and do not look "ricey" as you described. It's a matter of kelvin (color) and lumens (brightness). The CBI bulbs are 5000 kelvin, but throw a bright white sunlight color only found in the finest quality bulbs. No need to replace the factory ballasts either.
In short, the CBI's will NOT have that cheap blue tint of wanna-be HIDs, and still provide a long reach and wider beam than any other bulb. They are called 'cool blue intense' but there really isn't any blue hue - just pure daylight like the new Mercedes.
*** Beware though: about 80% of the dealers on Ebay, Craigs, and Amazon are selling knock-offs that are expertly crafted to look like the real brand name stuff. (not my opinion, but confirmed factual results). Be sure you buy from a reputable place. I recommend The Retrofit Source. They are one of only a few retailers who actually get the bulbs right from the factory instead of a wholesaler. Any brand bulb you get from them will be the legitimate bulb and not a knock-off.

You didn't ask about color for fogs, but 3,000k is the best for cutting through inclement weather and fog. Many people use the fog lights like an extra pair of headlamps (dunno why coz they only light a short area in front of the car and are aimed low towards the road making them useless for vision at night). Just know that the higher the kelvin, the less cutting through fog and the more distortion in vision when needed for foggy or rainy conditions.
Which HID's are ricey for a Platinum M35?
