Acuarela es cualquier pintura que sea a base de agua. Los ingredientes principales de la acuarela son pigmentos de origen vegetal, mineral o animal, amasados y aglutinados con agua y goma arábiga.

Watercolor is any paint that is water-based as opposed to being oil-based. The essential ingredients of watercolors are pigments, a binding agent (usually gum arabic), and water. When combined these three components create transparent watercolor.
