About this colour
Phthalo Blue (Red Shade) is the often neglected sibling of phthalo blue (green shade). Unlike weaker, warm blues like Ultramarine, Phthalo Blue (Red Shade) has the tinting strength necessary to retain brilliant colour when mixed with titanium white, making it an ideal warm blue mixing compliment for the modern painter. Its tinting strength is strong enough in fact to readily build passage of strong colour, despite being completely transparent. Use as a glaze to bring out its rich violet leaning blue undertone.
