DISEGNO Toolbar
Every tool on the brass bookmark leaves a mark, and its glyph draws that mark — chalk's tapered stroke, a wash's soft pooled blot, scissors mid-cut — rather than a picture of the instrument. The active tool sits lit in a dark recess; tools with color/tint variants grow a small brass tab beside the bar while they're selected.
Tooltips: roll the Apple Pencil (hover, no touch) or a mouse over any glyph and its label appears after a moment. On a finger with no hover, touch and hold a glyph — it shows the label instead of switching tools; lift without moving to just take a look.
Chalk
Chalk
The tapered stroke; tilt the pencil for the side of the stick. Has three color variants — tap the glyph again to reopen them.Red chalk (sanguine)
Black chalk
White chalk
Silverpoint
The unwavering hairline; only marks on prepared ground, and catches a soft glint under the light.Silverpoint ground
Coats the paper so silver can bite. Tint beside the bar:Natural — warm cream
Sanguine tint — terracotta
Powder green — sage
Ink & wash
Reed pen
The committed incised line; dwell with pressure to blot.Brush pen
Light touch for a fine line, press for a fat expressive stroke; never runs dry.Flat wash
Translucent, pools and darkens at the rim; press harder for a bigger, wetter pool that bleeds more into other wet ink and wash — never runs dry.Reed, brush and wash share the same three ink colors:
Bistre — warm brown (wood-soot, Renaissance)
Iron-gall — blue-black (Baroque)
Gold — opaque metallic ink
Clear water
Wets the paper, lifts and bleeds ink and wash.Frisket (masking)
Frisket
Cut a mask that blocks future marks; it never erases what's already drawn.Invert the cut — un-block instead of block
Lift mask from the drawing — block wherever marks already sit
Clear the mask — un-block the whole leaf
Pictures
Bring a picture
Arrange what lies on the pages — fragments and pictures wake under this tool. Blend modes: hold a piece with one finger and tap with a second to cycle it through Tincture's blends (multiply, screen, overlay, soft-light, color-dodge, color-burn, difference, luminosity, hard-light, back to normal) — a little tag names each as you go. The blend stays when you let go; it survives pinning, edge-gluing, page turns and exports, and only becomes permanent when you glue the piece down flat.Bring a picture onto this page — a GIF or APNG comes in moving
Bind a moving picture as a flipbook — its frames are dealt one per right-hand page, in the corner, so a thumb along the fore-edge plays it, on paper too
Choose a desk photo — it lies behind the book (choosing again replaces it)
Bare desk — put the photo away
Relic (kept gesture)
Relic
Draw with a kept gesture — take a scrap from the book's corner and every pen stroke stamps a copy of it in your last material. Drag sets size and angle; it stays in hand until you change tools.Keep a relic — arm, and the next stroke you draw with any tool is captured as a reusable gesture
Scissors & glue
Scissors
Draw across a torn leaf or picture to cut it — a loop snips a shape, a stroke slices in two. Drag the loose pieces apart, then tap a piece's pin to keep it (tap bare paper to drop whatever's left). Once kept, the knob turns a piece and the corners size it.Glue — tap a loose piece to press it into the paper forever, or draw the brush along one edge to glue just that edge (the piece stays a leaf you can lift, and what it hides is underneath). Tap an edge-glued flap with the glue again and it comes loose — edge glue is a fastening you can undo, like the pin; only pressing a loose piece flat is forever.
Pin — tap a loose piece to rivet it through its middle as a wheel: a finger turns it, and it keeps whatever angle you leave it at. Tap a pinned wheel again to work it free.
Glue down every loose piece on this leaf — the whole collage becomes paper
Guides
Guides
Scribe true lines to work to. Compass, straightedge and root rectangle are guides, not marks — nothing is inked, nothing is exported. The mirror is the one exception: its axis is never inked either, but its presence duplicates every real stroke as a live reflection.Compass — prick a centre and swing out a radius
Straightedge — rule a line between two points
Mirror — ruled like the straightedge, but it acts: wherever it's struck, every real stroke you draw is duplicated as a live reflection across it, in whatever material you're holding — the two sides pool and bleed into each other as one wet mark, not a copy pasted afterwards. The axis itself is still never inked. Place more than one for ad hoc multi-axis symmetry: a stroke reflects across all of them. Drawn solid, with fold ticks, so it reads as a mark that does something rather than one to work to.
Root rectangle — Barnstone's aid: drag out a golden-section or root proportion, sized by its own diagonal. Drag sideways for landscape, downward for portrait; several can sit on a page at once, for comparing a thumbnail-scale study against a full-page one. It sits last of the four instruments so its ratio picker stays directly beneath its own glyph.
Its ratio picker appears in the flyout while root rectangle is selected — each icon is drawn at its true proportion:
Golden section (φ ≈ 1.618) — the only ratio that also shows its gnomon cut, the mark of the square that would leave a smaller golden rectangle behind
Root-2 rectangle (√2 ≈ 1.414)
Root-3 rectangle (√3 ≈ 1.732)
Root-4 rectangle (√4 = 2)
Root-5 rectangle (√5 ≈ 2.236)
Snap — the pen is drawn to a scribed line while you work near it (drawing only — scissors always cut freehand). The mirror axis snaps like any other ruled line.
Sweep the scribed lines off the open pages — mirrors included, which is how you stop reflecting
Pastel (borrowed palette)
Pastel
Tap to import a TINCTURE palette as a temporary set of colors — a chalk stick's stroke, plus a torn paper tag marking it as a borrowed, temporary set. Colors appear as a grid of swatches; long-press a swatch that carries a fragment to lift its scrap into hand.Sort swatches by colour, value & temperature (tap again to sort by time)
Put the borrowed palette away — nothing already drawn or glued with it is undone
Its swatch grid and the sort/put-away actions now sit as two separately-sized plates — the grid can run wide for a big palette, while the two action icons below stay their own small width instead of stretching to match it.
