Water Harmony is a 24-piece watercolor pencil set from Cretacolors limited-edition Creative Garden Collection. All the colored and graphite pencils in the set can be blended with water:
17 water-soluble lightfast Marino colored pencils
6 water-soluble AquaGraph graphite pencils with color-accent
1 deep-black, oil-based charcoal pencil Nero, extra soft (carbon-graphite pencil)
When used dry, the pencils work like regular colored and graphite pencils. Add water and the pigments dissolve, transforming pencil strokes into washes of color and soft gradients. The water-resistant black Nero pencil adds dark accents that give your artwork depth.

For anyone who wants to try watercolor without starting with a paint set and palette. With water-soluble pencils, you draw as usual first and then decide where to introduce water. It is an especially controlled way to get started with watercolor techniques. The set is also an excellent choice if you want to combine color and graphite: AquaGraph pencils create atmospheric gray tones that can be layered with Marino colors. For watercolor effects, all you need in addition is a water brush and watercolor paper of approximately 200 g/m or heavier. Marino colored pencils and AquaGraph graphite pencils can be combined with all liquid watercolor paints.
