Sorry to bust into semantics, but the factory paint codes are just that - codes for PAINT. Powder coat is completely different, it is not paint. When "How It's Made" refers to powder coating as painting, it is a misnomer.
If you're using a painter, he can mix to achieve the code you desire. If you're using a powder coater, he cannot mix to create your factory color (he can mix them, but thats a crap shoot, not a scientifically calculated formula, like paint is). Unless a powder manufacturer has formulated a color-matched powder to match a given factory code, then all you can do is find the next closest thing.
That said, I had mine done last year, and not only do they look outstanding, but they're very close to the factory color, if not identical. If I recall, the color is called "Chrome," and it's a two-part color: the base, and the clear coat. Without clear-coating, the metallized powder base will oxidize. Your coater should know how to do this properly, although it's a bit pricier. Any bright silver powders should be pretty close, but I'm not so particular.
So you painting, or powdering?  |
Actually not quite correct....the powder coating industry DOES have a well established and accurate color specification and mixing system that is used in the INDUSTRIAL and aerospace powder coating and baked enamel industry....and is primarily a DIN based system but used world wide....
....and its also an issue that most general powder coating companies are little guys and do not do much industrial stuff...nor do they desire to spend the required money buy the proper spectrophotometric and lighting inspection booth equipment to properly verify colors.
Understand the need for this....like an aircraft company that has an ISO spec for color of powder coated parts that must be exact to within a Δ-E of less than 5 (human vision can discern color differences down to about a 3 Δ-E).......or an Architect working on a 50 story building that needs 600 sets of powder coated architectural balcony railings that are all the same EXACT color.
Most engineers and architects will specify their basic "colors" in the Munsell color system (which is also mil-spec)
https://en.wikipedia.org/wiki/Munsell_color_system
.....and when going to powder coat or baked enamel or ceramic "frit"...they have to convert to the RAL system which is used for powder coating, enamels and some plastic sheet casting work.
https://en.wikipedia.org/wiki/RAL_colour_standard
If you find a shop that does high end work...they can most likely convert and match. Sadly...most of those probably would not do wheels.

Actually, I am correct, and somebody as astute as you should read my posts more carefully. Nobody doubts the science behind the color indices used by powder manufacturers. But you're still not going to find some dude in a shop who's going to stand there and mix you a powder to match some factory color. Link me to one who will, and I'll eat my words.
Nice dissertation, anyway 
Anyhow, here's my powdered wheels in chrome silver. I'll update this post when I hear back from my guy with the manufacturer and official color name.

those are so beautiful

Got mine done today (5 wheels). This thread was the most helpful, so I'm posting these here.
The color we used was Bengal Silver.
Fresh out of the oven:
Mounted:
It was overcast today, so I'll have to wait until tomorrow to get some sunny pics.

Looks good. Where did you get your powder from?

| Is there a difference between L91 and L91 chrome or are they both the same colour code? |
