Ink vs Watercolor: Key Differences for Artists

publication · 2026-04-28

Watercolor paint uses finely ground pigment with a gum arabic binder, while colored inks vary by type—Dr. Ph Martin's inks use dye dissolved in water, and acrylic inks contain pigment with a polymer binder. Inks are more pigmented and retain saturation, making them ideal for vibrant compositions, but cannot be reactivated once dry. Watercolor allows reanimation with water, enabling blending and wet-on-wet techniques for subtle hues. My Modern Met Academy offers online classes on both media.
