Real watercolour: paint is pigment carried by water. It flows while wet, pools at the edges as it dries, settles into the paper's grain, and glazes over dried layers. Watch the dot next to the title: while it pulses, the sheet is wet.
| Pencil / stylus | paints; pressure sets size and load, tilt lays the brush on its side. Hover shows the brush. |
| Finger | paints until a pen is used, then navigates (Menu → Fingers). |
| Two fingers | pan, pinch to zoom, twist to rotate. Tap: undo. Three-finger tap: redo. |
| Long-press / Alt-click | pick a colour from the painting |
| Wet-in-wet | wet the paper with clear water (Q) first, then drop paint in and watch it bloom |
| Glazing | let a layer dry (or hair-dry it) and paint over it: colours multiply like real glazes |
| Mixing | tap + Mix (or Shift-click / long-press a well) to add pigments; they mix subtractively: blue + yellow = green |
| Granulation | Ultramarine, Potter's Pink, Burnt Umber, Cerulean settle in the paper's tooth; try Rough paper |
