HI. You may use Acrylic Colours to Paint the bottles but they are not scratch proof. Also the colours will not give the same finish as seen in the image. You may Sponge dab the color get soft texture and give two coats of colour to make it look even. Apply a layer of Clear varnish to protect the colour.
Even i wanted to know if there is any color, which can give the same finish is available at your store???
