An extensive palette of colors and their ease of use make Van Gogh watercolors an excellent choice for the demanding hobby painter. There are forty bright and intense colors, available in tubes and pans. Thirty-eight of the forty have the highest degree of lightfastness (+++). All colors are free of harmful heavy-metal-based pigment such as cadmium, lead and cobalt. They are easy to mix and can be washed into the most subtle nuances. colors in this line are extremely lightfast, even when heavily thinned, so work will last over many years.
