Holbein Artists' Nightfall Watercolor is a series of granulating transparent watercolors made with a black base. A granulating paint is one whose color separates into visible parts when you paint with it. "Nightfall" means the time when the sun sets and night begins. The colors are muted and calm, with a grainy texture.
There are 5 colors in 5 ml tubes: blue, green, red, yellow, and violet. Each color is sold on its own, and there is also a 5-color set.
The colors help other colors stand out, and each one is also easy to use by itself.
