Ecoline from Royal Talens are intensely saturated, dye-based liquid watercolors that are ready-to-use right out of the jar! Ecoline dries within minutes but can easily be rewetted, diluted, or mixed to create a plethora of unique hues. Color intensity is excellent and can easily be controlled by adding more water. Transparent and best used with watercolor brushes, airbrushes, water brushes, technical drawing pens, and broad-edge calligraphy pens on white or light-colored papers. Each 30mL jar features a built-in pipette for easy palette mixing.
