Styling and themes

Style one object from the ribbon’s Format tab or the Inspector, then spread that style across the diagram with copy/paste style, the eyedropper or a theme.

The Format tab

The ribbon’s Format tab, second after Home, holds the most-used appearance commands so a common edit does not need the Inspector. Every command applies to the current selection and dispatches the same edit the Inspector would, so either route is one undo step.

• Font: Bold, Italic and Underline toggles, plus Bigger and Smaller to step the label’s size.
• Paragraph: horizontal alignment (Left, Center, Right) and vertical alignment (Top, Middle, Bottom) for the label inside its shape.
• Appearance: swatch galleries for Fill (including No Fill, which keeps the colour but makes it fully transparent), Text Color (including Automatic, which picks a readable colour against the fill), Border Color, and a Border Style of Solid, Dashed or Dotted.

When a selection disagrees (some shapes bold, some not), the toggle draws in a mixed state, a dashed outline that is visibly neither on nor off. Clicking it makes the whole selection uniform. For colours beyond the galleries’ swatches, and for finer font weights, use the Inspector’s controls below.

The Inspector

The Inspector on the right edits whatever is selected. With nothing selected it shows document properties instead: title, author, canvas size, grid, units and rulers. Canvases themselves are renamed from their chip in the canvas bar, not here.

For a selected shape it offers:

• Fill: shape kind, fill colour, an optional gradient, and opacity.
• Stroke: border colour, width and dash pattern.
• Shadow: a drop shadow toggle with its parameters.
• Text: font, size, weight, alignment and colour for the label.
• Geometry: exact position and size in the document’s unit.
• Action: a hyperlink or other action the object runs.

Select several objects and the Inspector header reads Multiple Selection; every style edit then applies to all of them at once.

Reusing a style

Command	Shortcut	What it does
Copy Style	⌥⌘C	Picks up the style of the selected object: fill, stroke, shadow and text, without its geometry or label.
Paste Style	⌥⌘V	Applies the copied style to every selected object.
Style Eyedropper	⌥⌘I	Turns the pointer into an eyedropper: click a source object to pick up its style, then click each object you want to paint. Choose the command again, or press ⎋: to turn it off.

Note

To restyle a whole category at once, select one representative object, open Edit ▸ Find and click Select similar style. Every object sharing that style joins the selection, and a single Inspector edit changes all of them.

Themes

View ▸ Themes… opens the theme gallery: each built-in theme is shown as a preview of your active canvas drawn in that theme, so you choose by appearance rather than by name. An empty canvas uses a small example diagram. The built-in themes are Cool, Sunset, Forest, Mono and Vibrant. Your document’s current theme is the card with a checkmark.

The control above the grid decides what applying a theme touches, and the difference matters:

Mode	Effect
Keep my colors	Colours only the objects you have not deliberately coloured. Anything you or the AI assistant styled by hand keeps its colour. This is the safe choice for an existing diagram, and the default.
Recolor everything	Overrides every shape and connector, discarding hand-picked colours. Use it to reset a diagram to a clean palette.

Choosing a theme applies it and closes the gallery, in one undoable step (⌘Z). New objects pick up matching colours afterwards.

The theme is stored in the document itself, not only by name, so a diagram keeps the appearance you gave it when it is opened elsewhere. If a document names a theme this version does not have, the gallery says so and names it, and the diagram is drawn in the default theme until you pick one.
