Most places do these sort of effects by anodizing in one color first, then masking off certain areas you want a pattern to appear on (our Maskit product works well for this), then stripping the anodize.
The area that was masked won't strip and the color will remain. Then re-anodize the part a different color and repeat until you get the desired result.
I know you've posted your problem on PRS, with more details about your application, so it will be answered there. The first thing you should check is "does the part have an anodize layer?" You check this with a multimeter. If the part is not conductive, it has been anodized. We'll wait for your answer on PRS.
