The seven media
Watercolor, Ink, Pen, Marker, Pencil, Pastel and Charcoal, how each behaves, and why each has its own layer.
- Free
- Everything in this guide works in Free.
Paint a watercolor stroke, then tap Ink on the rim. Each medium paints on its own layer, so Doodly makes an Ink layer and says so at the top.

One medium per layer
Every layer holds one medium, because each medium is its own kind of paint: wet media run a water simulation, and dry media lay particles or film. When you take up a brush of another medium, from the rim, a ring or the library, the painting follows it:
| What the current layer is | What happens | The notice 2 |
|---|---|---|
| Empty | It becomes a layer of the new medium. | Empty layer changed to Ink |
| Painted, and a visible, unlocked layer of that medium exists | That layer becomes current. | Switched to its name |
| Painted, and there is none | A new layer of that medium is added. | Created Ink layer |
The notice shows beside the wheel, level with its bottom, where you made the choice. With Ask before a new layer on in Settings → Interface & input, a medium with no layer of its own asks first.
The layer strip and Layers 1 mark each layer with its medium's icon. Choosing a layer of another medium takes up that medium's brush. Free holds five paint layers of your own, and Plus as many as your device holds; the layers a book's fill makes never count. A medium takes over an empty layer before it makes a new one. When they are all in use, show and unlock a layer of the medium, or clear or delete one, to use the brush.
How each medium behaves
| Medium | Kind | How it behaves |
|---|---|---|
| Watercolor | Wet | Transparent pigment carried by water. Wet strokes spread, run into each other and bloom, granulate into the paper's texture, darken at their edges as they dry, and can be re-wetted and lifted. |
| Ink | Wet | Liquid, strongly staining ink. It feathers along the paper, pools at its edges and dries permanent: Ink has no Lift. |
| Pen | Dry | A crisp line at an even tone, for drawing and lettering. Its marks can glow on a dark painting. |
| Marker | Dry | Translucent layers that darken where they overlap, with a little bleed into the paper. A Marker layer already multiplies, so it has no blend mode to choose. |
Watercolor, Ink and Marker are transparent: on light paper a colour darkens what is under it, as real washes do. White and near-white paint in them, and every colour on dark paper, lie as opaque body instead, like gouache, white ink or a paint pen, so a white highlight shows over a darker wash and a painting on black paper shows its colours. | Pencil | Dry | Graphite tone that catches the paper's tooth; pressure and tilt shape it. Smudge, Blend, Lift and Dust tools. | | Pastel | Dry | Soft, chalky particles that sit on the paper's peaks and fill its valleys as you press. Smudge, Blend, Lift and Dust. | | Charcoal | Dry | Like Pastel, with a stronger black and finer breakup. Smudge, Blend, Lift and Dust. |
Wet media are covered in Watercolor and ink, and the tools that soften and move paint in Blending tools.
Brushes in each medium
Each medium has its own brushes, from fine to broad, some that move by themselves (Living Wash, Living Sumi, Living Line and so on), mark brushes that lay shapes or effects, and its tools. Every medium also takes every motion and every effect, from the Motions and Marks collections of the brush library.
Tip: Every medium is Free, with all of its brushes and tools.
