You can use Inktense pencils dry, but mix them with water and the color turns into vibrant ink. Once dry the color is fixed and you can work over the top of it, and, because it's permanent it's great for using on fabric such as silk and cotton. Set colors include Sherbert Lemon, Sun Yellow, Tangerine, Poppy Red, Chilli Red, Shiraz, Fuchsia, Violet, Iris Blue, Bright Blue, Deep Indigo, Sea Blue, Teal Green, Apple Green, Field Green, Leaf Green, Mustard, Baked Earth, Willow, Bark, Charcoal Grey, Black, Antique White and Outliner.
