Extra-Fine Watercolors in Tubes – Cobalt Blue (Royal)

Extra-fine watercolors are traditionally formulated with gum water, honey, and glycerin. The line includes about thirty colors, all of which are single-pigment. The pigments in this line are pure and non-toxic. Most of the selected colors are permanent, with the exception of the subtle and irreplaceable natural plant-based colors. The blue comes from genuine dyer’s pastel. Genuine madder red lac, woad yellow lac, walnut lac, and Maya blue are derived from cultivated plants.
