Color Wheel: Show Document Colors lists the colors the art uses - #7641
Builds on #7602; until it merges, this diff also shows its commit.
What and why
Part of #978. The Color Wheel panel can show the colors the art uses in a row under the wheel or the box. This is VectorCraft's own addition to the panel.
The panel menu has Show Document Colors. With it on, the row lists the colors of the selection, headed Selection Colors, or with nothing selected the colors of the art Select All takes, headed Document Colors. The most used color comes first, and the row holds as many colors as fit on one line.
A color's tooltip gives its hex value and how many times the art uses it. Screen readers read the same text.
A click applies the color as a pick on the wheel does, in one undo step. The active proxy and a selected gradient stop keep the color's model and its link to a global swatch at its tint. A selected freeform point takes the color alone. Alt+click applies the color to the inactive Fill/Stroke proxy.
The row reads the colors again when the document or the selection changes, and not during a drag. In art with more than 5,000 color uses, an edit reads them again at most once every half second.
color.used {selection?, limit?} lists the colors recolor.colors counts, each with the color in its own model and, when it is linked to a global swatch, the swatch and its tint to three decimals. The swatch and tint come from the color's first linked use in paint order, and a plain use goes before a gradient stop that mixes a spot ink with process inks. A color that only such stops link has no swatch. recolor.colors answers as before.
ui.colorWheel takes documentColors (true or false) and returns it. The setting is kept with the preferences and read leniently.
New strings have rows in every catalog, next to the other Color Wheel rows. docs/control-protocol.md, docs/mcp.md, the ui.colorWheel params text and a line after the Color Wheel panel entry in docs/target-app-parity.md describe the change.
How it was tested
crates/ui-egui/src/panels/tests_color_wheel_document_colors.rs adds 12 tests: the order and counts, the heading following the selection, the row's width limit, a click on the fill, Alt+click on the stroke, a click keeping a swatch link and its tint, a click on a selected gradient stop, no new read during a drag, the half-second wait in large art, the panel menu, ui.colorWheel and the saved setting. crates/engine/src/tests/recolor.rs adds 4 tests for color.used: order, limit, uses and selection; the swatch and tint, also in a pattern tile; a stop that mixes its ink with process inks; and a plain linked use painted after such a stop. Each new test fails with the code it covers broken.
On Linux, at b83cec15 on #7602's head 22b8c6ce (on main at a47d7eec):
The branch merges with main at 67f6d3a5 without conflicts, and cargo check --workspace --tests passed on the merged tree. This branch, #7617, #7629, #7630 and #7632 all add Color Wheel panel settings, menu items and catalog rows, so each one that merges after another needs those files merged by hand.
No panics in shipped code: no unwrap(), expect(), panic!, unreachable!, todo! or unimplemented! outside tests, and no unchecked indexing on data from files, parameters or
messages. Errors are returned as Result and shown to the user
(why and how).
Clean-room: nothing copied from Adobe products or GPL/AGPL code (AGENTS.md).
Every new asset has a row in ASSETS.md.
Summary by CodeRabbit
New Features
Added a Box view to the Color Wheel, with selectable color channels and keyboard controls.
Added an optional Document Colors row to browse and apply colors from the selection or artwork. Linked swatches and tints are preserved when applicable.
Added color.used to report color usage, including counts, ordering, color values, and linked swatch details.
Color Wheel view, channel, and Document Colors settings can be changed and saved through the control interface.
Documentation
Documented the new Color Wheel settings and color-usage query.
… color field and a channel strip
The Color Wheel panel's menu gains Wheel View and Box View, and Box
Channel with Hue, Saturation, Brightness, Red, Green and Blue while the
box shows. The box takes the wheel's place: a color field with a 22 pt
channel strip at its right. The field shows the other two components on
the Color Picker's axes (Hue: saturation across and brightness up; Red:
blue across and green up). A click or drag in the field sets those two,
and the strip sets the channel; a drag is one undo step, and picks go
through the same paint commands and color model rules as the wheel's.
With no color to edit, the field and the strip show no markers and read
0 to screen readers, as the wheel does.
ui.colorWheel {view?, channel?} sets the view and the channel and
returns them. Params that are not an object, another key or a value off
the list are an error and change nothing. Both settings are kept with
the preferences, and a saved value the build does not know reads as
that key's default without losing the other preferences.
The strip takes the arrow keys after a click and offers screen readers
its increment, decrement and set-value actions. The Color Picker's
channel slider uses the same widget, so it now takes the arrow keys and
offers those actions too. New strings have rows in the complete
catalogs, and docs/mcp.md and docs/control-protocol.md describe the
command.
The Color Wheel panel menu gets Show Document Colors. It adds a row
under the wheel or the box with the colors of the selection, headed
Selection Colors, or with nothing selected the colors of the art Select
All takes, headed Document Colors, most used first and as many as fit
in one row. A color's tooltip gives its hex value and how many times
the art uses it. A click applies it to the active proxy or to the
selected gradient stop, keeping its color model and its link to a
global swatch, or to the selected freeform point, which takes the
color alone. Alt+click applies it to the other proxy.
The row keeps its colors during a drag. In art with more than 5,000
color uses, it reads them again at most once every half second after
an edit; a change of document or selection reads them at once.
color.used {selection?, limit?} lists the colors recolor.colors lists,
each with the color in its own model and the tint of its swatch to
three decimals. The swatch and tint come from the color's first linked
use in paint order, a plain use before a gradient stop that mixes a
spot ink with process inks; a color that only such stops link has no
swatch there. ui.colorWheel {documentColors} sets the option, which is
kept with the preferences.
Docs: docs/control-protocol.md, docs/mcp.md, docs/target-app-parity.md.
The change adds the color.used query and extends the Color Wheel panel with persistent view settings, a configurable Box View, and a document-color row. The panel can display colors from selected objects or the document and apply a clicked color to a paint target.

Summary
Color-use query and serialization crates/engine/src/cmd/plugin_call/reviewed.rs, crates/engine/src/cmd/recolor.rs, crates/engine/src/tests/recolor.rs, docs/control-protocol.md
The engine adds color.used for selection or all-art color counts. Results include model-preserving color values, qualifying linked-swatch and tint details, use counts, and an optional result limit. Tests cover ordering, scope, tint metadata, and mixed gradient stops.
Color Wheel settings and command crates/ui-egui/src/panels/color_wheel.rs, crates/ui-egui/src/state.rs, crates/ui-egui/src/menus/*, crates/ui-egui/src/panels.rs, crates/mcp/src/ui_catalog.rs, crates/ui-egui/src/panels/tests_color_wheel_box.rs, docs/control-protocol.md, docs/mcp.md
The panel stores its view, box channel, and document-color visibility settings. The ui.colorWheel command validates and updates these settings. Menu controls and command documentation describe the options.
The panel can render a configurable color box instead of the wheel. Channel sliders support keyboard and screen-reader value changes. Tests cover color selection, interaction, accessibility, and coordinate conversion.

The row displays colors from the selection or document, with cached results and refresh throttling for large artwork. Clicking a color applies it to the active or inactive paint target and preserves applicable swatch links and tints.

The document-color row can miss colors that appear only inside nested patterns. Resizing the panel can also trigger extra color scans in very large documents. Both are minor and do not break core editing, but each deserves a follow-up fix.

Include colors from nested pattern tiles.
If a selected square uses pattern P, and P's tile uses pattern Q whose tile is red, color.used can return an empty palette. This callback puts Q into a temporary vector and discards it. The red fill never reaches the counter.
Collect nested pattern names in a shared worklist. Process each pattern once, including when patterns form a cycle.

- `recolor.colors`, `recolor.reduce` and the recolor groups name the swatch of a color's first
linked use again. Only `color.used` takes its swatch and tint from the first linked use that is
not a gradient stop mixing a spot ink with process inks.
- A row wider than 128 chips asks `color.used` for as many colors as it holds.
- The new catalog rows sit with the other Color Wheel rows.
- Tests cover a click on a selected freeform point, the tint a click gives a selected gradient
stop, a row wider than 128 chips, and `recolor.colors` with a mixed stop painted before a plain
use linked to another swatch.

Minor · Performance & Scalability · Quick win
Keep the interaction and throttle guards on widening refreshes.
When the cache holds 128 colors and the row widens to 129 chips, the reuse condition at line 227 is false. The block is skipped, and the next color.used query runs without the in_interaction() check or the 0.5 s throttle. Each one-chip widening step repeats this, so a resize across chip boundaries reads the colors on each step. For a document with more than 5,000 color uses, each read is a full color scan.
Evaluate the interaction and throttle guards before the capacity check decides whether to query. The capacity check should only decide whether the cached colors can be reused.

With this change, a widened row keeps its cached colors during an interaction. The row shows fewer chips until the interaction ends, as the design intends. A regression case should widen a full cache during an interaction and within the throttle window, not only start with a wide row.
