Hi, Ernesto. Yellow, rose, and green are all done basically the same way with small variations in the quantity of contaminating metals. Do you know how to do gold electroplating yet? I haven't heard of 'white gold plating', but white gold jewelry often receives rhodium plating. Please get back to us with more info on your situation.

Dear Ted, in the Philippines we usually refer to white gold plating when we use rhodium, and dorado in yellow gold plating. my problem is how to produce rose gold (light red color) when plating yellow gold? any idea on the chemical to add or mix? please help.. thanks

Ernesto,
First we have to know what type of gold bath(s) you are using now. Color golds are usually cyanide gold baths with different metals added as a liquid. We could tell you to add so much of this, and so much of that. Would it be the color you desire? Probably not. If you have a reputable gold bath supplier they may plate up some samples for you, or they can suggest beaker lab tests to achieve the color you are looking for. Good Luck!
