What it is and what it does. Rose gold colouring agent is the chemistry used to give a pink-rose gold tone to hardware, either as a coloured deposit or as a colouring treatment on an existing gold or copper layer.
- Pink to rose coloured clear liquid, dosed into the working bath to set the tone.
- Rose gold tones come from the copper to gold ratio; the colour agent controls the balance in the deposit.
- Increasingly used on fashion hardware and jewellery findings as an alternative to solid rose gold plating costs.

Buyer Questions We Answer Every Week
| Question | Answer |
|---|
| What determines the tone, the chemistry or the current? | Both - the bath chemistry sets the working range and the current density fine-tunes the shade, so both must be held constant. |
| Does the colour need a topcoat? | For wear resistance a clear lacquer is recommended, as with other decorative colour finishes. |
