Because the paints are formulated to stay workable longer than standard acrylics when used with the included OPEN Thinner, the set is suited to techniques that benefit from extended blending, such as portraiture, plein air glazes, and layered colorwork. The selection of 22 ml tubes offers a compact, portable kit for studio or outdoor sessions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat colours are included and why those choices matter?\u003c\/h3\u003e\n\u003cp\u003eThe set contains twelve versatile pigments chosen to cover a broad gamut while supporting the split-primary mixing method.
