Designed with the illustrator and fine artist in mind, non-toxic Createx Illustration Colors are optimized for re-wettable techniques and soft erasing. Made with the same lightfast, exterior-grade pigments as Createx Wicked Colors and Auto Air Colors, Createx Illustration Colors use a different resin binder that renders them re-wettable with an ammonia-based cleaner such as Windex. They are also very easy to erase within the first 48 hours after application. The heavily pigmented colors dry to a matte finish. They appear glossy and vibrant with dimension after a clear gloss topcoat clear is applied. Because of their extremely low viscosity, many artists find that Illustration Colors offer excellent performance straight from the bottle, with no reduction necessary. They can, however, be reduced and over-reduced in any ratio with 4012 and 4020 Reducers. Createx Illustration Colors may be sealed with a clear urethane for permanence. Note — Createx Illustration Colors are suitable for application with airbrushes only and are not recommended for use with spray guns.
