Watercolor and ink
How much water a brush carries, wet paint running together and blooming, drying, wetting or drying a whole layer, and replaying the drying.

Tap the Water gauge for the brush's settings, and turn Water right down. With little water, watercolor stays where you put it.

Water
Watercolor and Ink are wet media: paint moves in water on the paper until it dries.
- Water 1 on the wheel's ring sets how much water the brush carries. Drag it clockwise around the ring, the way its fill grows, for more; tap it for a large slider. Low water keeps a crisp, dry-brush mark that catches the paper's grain; high water spreads, softens and runs.
- On Brush Studio's Paint page, Water is the same value, beside Strength, Staining, Edge darkening, Edge grain, Spreading and Pencil push.
- Water dims on the wheel when the layer is a dry medium.
Wet into wet, blooms and drying
Strokes that meet while wet run into each other, so colours mix on the paper. Water or paint dropped into a damp wash pushes pigment outward into a bloom with a darker edge; Bloom Water and Wet Round are made for it. Edge darkening sets how strongly pigment gathers at the edge as a wash dries; above about two thirds, the wet pigment runs out to the wash's rim and dries there as a dark ring. Hard Edge and Puddle are made for that, while Wet Round dries soft. For broken, grainy marks, Dry Brush and Dry Flat carry no water, and Damp Brush carries a little, so it streaks where it drags. As paint dries it stops moving, keeps its edges and settles into the paper's grain. Drying waits while you draw a stroke, so a wash beside the one you are laying stays as wet as it was when the Pencil touched down. Staining pigment binds to the paper; non-staining pigment can be lifted again while wet.
Ink behaves like watercolor while wet, feathering along the paper and pooling at its edges, but it dries permanent: it can't be lifted.
Wet layer and Dry layer
Tap the current layer in the layer strip, or open Layers, and a watercolor or ink layer offers:
| Control | What it does |
|---|---|
| Wet layer 1 | Wets the whole layer, so the next strokes go on wet-on-wet. |
| Dry layer 2 | Dries the whole layer at once, so the next strokes glaze over it without mixing. |
| Current (in Layers) | A gentle, steady current that keeps moving the wet paint on the layer. |
Each is one step you can undo. Wet and Dry layer are dimmed while the layer is locked or hidden. With a panel or colouring-page area chosen (Choose area, see Panel layouts), they wet or dry only that area.
To wet or dry just part of the page, use the Water Brush and the Dry Tool; see Blending tools.
Replaying the drying
Drying is not part of the painting's loop: once paint has dried it stays dry while the painting plays. Actions → Playback → Replay drying runs every wet layer again from the start, so you can watch the paint spread, meet and dry. Play from the start only restarts the motion.
Tip: Wet paint needs the painting to be playing to move. If a wash looks still, check that the play button in the top bar isn't paused.
