# Art Media and Techniques

A style description becomes more useful when it identifies **medium**, **support**, **mark-making**, **edge quality**, **palette**, and **finish**:

```text
gouache on cold-press watercolor paper, opaque simplified shapes, dry-brush edges,
visible paper tooth, limited ultramarine, ochre, coral, and cream palette
```

## Drawing media

| Medium | Characteristic appearance | Prompt cue |
| --- | --- | --- |

## Ink and line techniques

- **Contour drawing:** outlines describe boundaries with minimal interior tone.
- **Blind contour:** wavering observational line made without looking at page; raw and intimate.
- **Continuous line:** one unbroken path constructs the entire subject.
- **Cross-contour:** lines wrap around form to show volume.
- **Hatching:** parallel strokes build value.
- **Crosshatching:** intersecting hatch layers deepen tone.
- **Stippling:** dots vary in density for tone and texture.
- **Scumbling:** loose tangled small marks create broken tone.
- **Scribble shading:** layered loops or irregular strokes build energetic values.
- **Line-and-wash:** ink drawing combined with transparent watercolor washes.
- **Ink wash:** diluted ink forms atmospheric monochrome values.
- **Sumi-e:** economical East Asian ink painting emphasizing brush energy, negative space, and tonal ink.
- **Dry brush ink:** bristles skip over paper tooth, creating broken textural strokes.
- **Spatter:** droplets create random energetic texture.
- **Calligraphic line:** stroke weight and taper carry expressive rhythm.
- **Engraving-like line:** controlled parallel and curved hatching imitates incised print lines.

## Water-based painting

| Medium | Properties | Useful specificity |
| --- | --- | --- |
| Transparent watercolor | Luminous washes, paper white as light, blooms, granulation, layered glazes. | `wet-on-wet sky, dry-brush foreground` |
| Gouache | Opaque matte color, flat shapes, reactivated edges, possible dry brushing. | `opaque gouache editorial illustration` |
| Acrylic gouache | Flat matte opaque color with more permanent, even layers. | `acrylic-gouache poster shapes` |
| Tempera | Fast-drying matte paint, crisp strokes; egg tempera supports fine layered detail. | `egg-tempera panel painting` |
| Casein | Opaque milk-protein paint, matte and velvety, suitable for illustration. | `casein landscape study` |
| Acrylic | Versatile polymer paint from transparent glaze to thick opaque impasto. | Specify fluid, heavy-body, airbrushed, or poured. |
| Fresco | Pigment integrated into wet plaster, matte mineral color, wall-scale joins. | `buon fresco mural` |

### Watercolor behavior terms

- **Wet-on-wet:** soft expanding edges and intermingled color.
- **Wet-on-dry:** controlled shapes with defined boundaries.
- **Glazing:** transparent dry layers build depth and color.
- **Granulation:** pigment settles into paper texture in mottled clusters.
- **Bloom / backrun:** water pushes pigment into cauliflower-like edges.
- **Dry brush:** nearly dry pigment catches paper high points.
- **Lifting:** pigment removed to recover pale shapes or highlights.
- **Salt texture:** crystalline mottling formed during drying.

Avoid chaining unrelated media unless a mixed-media result is intentional. One primary medium plus two or three process traits usually produces a clearer visual identity.
