Winsor and Newton has been making paint for artists for the past 180 years. Each color is made to have stable color. The company makes sure that the quality control process keeps the paint ready to be what artists need and want. All their paint becomes touch dry within two to twelve days.
Terra Rosa is Latin for red earth. W&N uses a synthetic iron oxide pigment, which is named Mars orange. The color itself is a warm, brown, red pigment. The paint itself is permanent and opaque. Another name for the color is Bole, from the Latin bolus. Bolus means lump of earth.
The color itself was used in Medieval Italian wall paintings. That means that Terra Rosa would be used for recreating such paintings for an art class. The color is also good for tinting canvases.
