Sanguine, a rich, earthy red chalk, became a favorite among Renaissance artists for its versatility and warm tone, which offered a striking contrast in sketches and preparatory studies. Michelangelo’s use of sanguine in his "Studies for the Libyan Sibyl" showcases its ability to capture both detail and expression, allowing artists to convey a sense of volume and form with incredible finesse. When working with sanguine, one common mistake is pressing too hard, which can leave harsh lines that detract from the subtlety of a piece. A great tip is to start lightly and build up layers gradually – this way, you maintain control and can enhance depth and texture without compromising the softness that sanguine is celebrated for!
