colour matching powder coating

[justin]

Hello, I want to get the engine guard on my FJ powder coated to match the rims. I know that the colour of the rims is 1329 deep purplish blue metallic DPBM15. Only problem is that powder coating uses a different chart and that colour information means nothing to the business I will bring the guard to. I was wondering if anyone ever did get some powder coating done that would know what number that would match the rims. I feel as the closest would be #5002 on the chart but may be a mix of two colours. What do you guys think? The link below is for the colour chart.

thank you

If you can't find a powercoater that won't try to match, find a new one.
Personally, not like these wheels are going to see a lot of rocks and chips and the wheel pattern is easy to paint.

Just get them painted with an extra shot of clear.  They will be easier to clean.

I am a print color specialist in my day job, and what I can tell you is that trying to match your rim color to a swatch chart on a web page is futile. In fact we're probably all seeing vastly different colors when we visit the Ralcolor website on our various computers, phones, etc. How that color actually looks on a metal substrate like your wheels is probably way off. 

Ask the powder coater if they have a portable spectrophotometer, like this:

eXact™ Standard | X-Rite Handheld Spectros

eXact™ Standard

I have one of these at work. Yes, it was expensive. A spectrophotometer can be used to precisely measure the color of your rims in LAB values. These LAB values can then be used to map to some color in whatever system the powder coater is using. I see that Color Rite sells paint in the Yamaha 1329 color, but of course they don't reveal LAB values on their website.

I did not know a spectrophotometer actually existed. I will definitely asked if he does have one if not ill check other powder coating shops see if anyone has one. Thank you for your help really appreciate it.

It's possible the guys at the powder coater don't know what a "spectrophotometer" is, but they might have a "color scanner" or sensor which is actually just a spectrophotometer. It measures the spectral wavelength of reflected light relative to a known white point (usually a white chip inside the scanner's cap). Color data can be reported in CMYK, RGB, or LAB. CMYK and RGB values are arbitrary and therefor useless, so what you want is the LAB value. LAB defines a single human-visible color, which can then be translated to any other color output system. 

All that said, I would be surprised if many powder coaters are capable of scanning colors and performing true color matching in the same way a paint shop can. I don't know what sort of colorants are used in powder coating, but in my experience they usually only offer a limited range of colors.

my guts tells me your right when it comes to the colour matching, but powder coating is the best way to go. I just hope I can get a  colour that is very close to the rim as I think it would look cool, plus would add a personal touch to my FJ.
