The best means of applying pearlescent colours is by using a dipper pen, ruling pen or brush. These acrylic based inks are water soluble when wet but dry to a water resistant film. All colours are good to extremely light-fast. The shimmering pearl effect created by these colours is startling. All colours are inter-mixable. They are permanent and translucent, but work best is put down freely rather than applying successive layers of colours. There are many interesting and exciting ways of using FW Pearlescent Inks.
