There's a reason why watercolor painting is so popular. Not only are the paints more affordable than their acrylic and oil counterparts, but their portability makes them ideal for artists to work en plein air. However, there's more to watercolor painting than pans and tubes. Watercolor mediums are a great way to enhance your artwork in unique and creative ways. They are used in addition to pigment and have specific features that change a characteristic (or characteristics) of your paint.

Most watercolorists are familiar with the standard watercolor medium—which enhances transparency and vibrancy—but there are many other kinds available. The iridescent medium, for instance, adds a glittering pearlescent effect when mixed with wet paint or applied on top of dry layers. You can also achieve a mottled effect by diluting colors with a granulation medium.
