There is such a wide variety of paints and surface treatments for polymer clay and as clayers we never have enough ! I recently bought some colour changing paints which are luscious metallics with an undertone. The paints used are Color Shift by Folk Art 

I initially made a necklace to which I added the paints prior to curing and there was a substantial change in the colours, so I decided to do some test pieces and experiment. I made squares of black and white clay (I used Premo), covered one set of squares in the four paint colours I had. I cured these squares together with some unpainted squares for 30 minutes

Once out of the oven I added paint to the previously unpainted squares and now I had a good indication of changes in colour. If paint is added and cured, the luminosity disappears somewhat and we get  more subtle colours, which I rather like. If you add to blank cured clay, you get more true colours.. Dont forget that you can increase intensity of colour by letting one layer of clay dry and adding another.

Making Jewellery with Polymer Clay and Paints

This pendant was made by adding paints before curing and provides a mini tutorial for you (intermediate clayers) Please ask questions or leave comments if you like

Supplies Black polymer clay, liquid clay, clay knife, cutters and blades, silk screen of choice (mine was from Tonja Lenderman) paint brush, pan pastels (not essential) white acrylic paint, Color Shift Paints (available in the UK from Clayaround)

• Silk screen your black polymer clay with the white paint (if you wish to paint your piece before curing)
• Paint the gaps in the design with your colour change paints, once the white clay has dried
• Once fully dried, cut out your jewellery shape over a further pice of black clay which will give you the required thickness for your piece. NB I have not specified settings on pasta machine as all machines are different and if comes down to personal preference
• Add Pan Pastels to background and burnish in, you can also add a bail at this stage if required. I then distressed my background by adding texture and scoring
• Place piece in oven for a 30 minute cure at recommended temperature. If you havent added a bail previously, you can do this now or add more backing. Cover the piece in liquid clay as this enhances the colours and cure for another 30 minutes
