Closes #1298

What changed

The Style tab's Drawing group has a colour button labelled "Color" above "Outline" and "No Fill". It changes a polygon's fill and a point marker's fill, never the outline colour (layer.color leaves a polygon's outline alone; the ribbon only has an outline width). The label read as the outline colour.

• Polygon and point layers: the button is now Fill.
• Line layers: still Color, since a line has no inside and the button sets the line's colour.

The Symbology pane's Symbol box named the same button "Color" too, so it now says Fill as well (the contributing guide asks for one name per command across the ribbon, panes and Command Search).

Labels only. No command, saved-file or setting changes. "Fill" is already in the translation catalogs.

Tests

• New drawing_names_the_colour_by_what_it_changes (Countries and Cities show "Fill", Rivers does not).
• cargo xtask ci passes here except settling_after_a_camera_animation_re_renders_fully (gpu_fastpath), which test(ui): wait for a flat map's off-thread settled frame in the GPU settle test #1785 reports failing on main since UI: draw a flat map's settled frame off the UI thread (#1750) #1775. This change touches only interface labels, not rendering.

Notes

• A layer with several geometry kinds is named by geometry_type() (one kind), so one with lines and polygons may still say "Color".
• The reporter hasn't yet answered whether they meant a different control (see my comment on [Feature]: Change to the color button in the Drawing group #1298).
• Command Search still names the command "Symbol Color". Renaming a command's title is a separate change to the engine, so it is left out here.
• No code followed from other projects.

Walkthrough

The Drawing group now labels its color control “Color” for polylines and “Fill” for other geometry types. The symbol editor’s fill-color control also uses “Fill”. A test checks the Drawing group labels for polygon, point, and line layers.

Merge Risk: Minimal · up to d9923

The change renames the Drawing group's color button to "Fill" for polygon and point layers. The button's behavior is unchanged, and there is no merge-blocking risk. A possible follow-up is to link the visible label to the color well for screen readers.

Code review

Overall: the change is small and correct as far as I can verify by reading. I could not compile or run the new test (no build tool in this environment), so that check is by reading only.

Bugs

• None found. The label and the behaviour use the same value. drawing_group reads layer.geometry_type() (ribbon.rs:4406), and layer.color uses l.geometry_type() as its g (engine/src/cmd/layer.rs:224). So a mixed layer's label matches what the button changes. The PR's stated caveat for mixed layers is consistent with this. Confidence: high.
• GeometryType is already imported, both tl! branches return the same type, and "Fill" is in the catalogs (e.g. i18n/fr.tsv:1403). The Drawing group only renders for non-None layers (ribbon.rs:2390, 3924).

Security

• None. The change is a label.

Performance

• None. geometry_type() is a field read.

Quality

• Nit, low severity: drawing_names_the_colour_by_what_it_changes (ribbon.rs:5297) asserts only that "Fill" is absent for Rivers. It never checks that a label is present there, so the test would still pass if the Polyline branch rendered nothing. The colour well is also labelled "Color", which is why the test can't assert on "Color" directly. This is a test-strength point and may wait for the release quality pass. Confidence: high that it is weak; low that it matters.
• Observation, not introduced by this PR: Command Search still names layer.color "Symbol Color" (engine/src/cmd/layer.rs:217). The ribbon now says Fill or Color. The Symbology pane already uses the same Fill/Color split (panes.rs:5673–5680), so the ribbon now matches the pane. The ribbon guidelines ask for one name per command across ribbon, panes and Command Search. Confidence: medium that this is in scope.

AGENTS.md

• Screenshots: the PR body says "Before and after screenshots are attached below", but the body contains no image link or attachment. AGENTS.md requires before and after screenshots for a visible change. The staged body may have lost them, so please confirm they are actually on the PR. Confidence: medium.
• The test uses .unwrap() in a test module. This follows the existing tests in the same module, so it is consistent with the repository. Not a violation.

Already raised

• No prior review threads exist on this PR, so none were left alone.

Review comments at @crates/ui-egui/src/ribbon.rs:
- Line 5303: The line-layer assertion only verifies that “Fill” is absent, so it
can pass when the label is missing or incorrect. Update the Rivers case in the
test to assert that the visible label is “Color” explicitly, separately from the
color well’s accessible-name assertion; preserve the existing “Fill” check for
fill layers.
- Line 4407: Associate the text label created by ui.label in the color-well
rendering path with the well’s response, so screen readers identify the control
as Fill for polygon and point layers rather than only Color. Preserve the
existing label text and styling.

📖 Docs preview

Commit d99238d from a fork built, but isn't published until a maintainer adds the preview label (once per commit).

[github-actions]

Nit (naming, non-blocking): the same layer.color command is still labelled "Color" for polygon and point layers in the Symbology pane (crates/ui-egui/src/panes.rs, symbol_editor, about line 5212), and its command title is "Symbol Color". After this change the ribbon says "Fill" for that command. docs/contributing.md › Ribbon guidelines asks for one name per thing across ribbon, panes and Command Search. Aligning the pane label, or noting the difference in the PR, would satisfy that. Naming can wait for the release quality pass if you prefer.

[github-actions]

Code review

Bugs: None found. The new label follows layer.geometry_type(), the same check layer.color uses (crates/engine/src/cmd/layer.rs:224). For polygon and point layers it sets the fill (with_fill, crates/map/src/symbology.rs:157), and for line layers it sets the line colour. "Fill" and "Color" both exist in the i18n catalogs, and the GeometryType::None case never reaches this group.

Security: None found. The change is label-only.

Performance: None found.

Quality:

• Naming, non-blocking (posted inline on ribbon.rs:4406): the Symbology pane (panes.rs, symbol_editor) still labels the same layer.color command "Color" for polygons and points, and its command title is "Symbol Color". The ribbon guidelines ask for one name per thing across ribbon, panes and Command Search. Confidence: medium-high. Naming can wait for the release quality pass.
• Mixed-geometry layers are named by their declared kind only. The PR body already notes this, and the label stays consistent with what the command does. Confidence: high that it is a known limitation, not a defect.

AGENTS.md: Nothing broken. The change adds no new strings beyond the existing "Fill", includes before/after screenshots, and the test uses unwrap only in test code, which clippy.toml allows.

Already raised, left alone (2):

1. Colour well's accessible name still reads "Color" while the visible label reads "Fill" (ribbon.rs:4407). The thread is unanswered and the code is unchanged.
2. The Rivers assertion checks only that "Fill" is absent, not that "Color" is shown (ribbon.rs:5303). The thread is unanswered and the code is unchanged.

Code review

PR #1784 relabels the Drawing group's colour button "Fill" for polygon and point layers and keeps "Color" for lines. The change is correct, and I found nothing that needs an inline comment. I reviewed by reading the diff and the surrounding code only; I did not build or run the tests.

Bugs

• None found. The ribbon (ribbon.rs:4406) and the Symbology pane (panes.rs:5211) both key the label off the layer's geometry type, so they agree. Raster layers go through raster_style_groups and never reach drawing_group, so "Fill" can't appear on a raster. layer.color changes a polygon's fill and a point's marker fill, so "Fill" names what the button changes.
• Confidence: high.

Security

• None found. The change is label-only and adds no input handling.

Performance

• None found.

Quality

• Mixed-geometry layers are still named by their dominant family, so a layer with lines and polygons may say "Color" for a button that sets polygon fill. The PR description already notes this. Confidence: high that it's a limitation; low that it needs a fix now.
• The test comment at ribbon.rs:5302 says the colour well is itself labelled "Color". I could not confirm that from the code read here. If it is wrong, the comment misleads, though the assertion still holds. Confidence: low.
• The geometry_type() == Polyline branch now appears in both the ribbon and the pane. A shared helper would keep them in step, but that is a refactor and can wait for the release quality pass.

AGENTS.md

• Compliant. Both new labels go through tl!, and "Fill" is already in the catalogs. The PR attaches a before/after screenshot for the visible change, and the new test checks both the presence and the absence of the label. No new dependencies, unwrap only in test code, and no layering change.

Earlier concerns

• Two earlier concerns were left alone because they were already raised: the CodeRabbit note that the ribbon label is not associated with the colour well (ribbon.rs:4407), and the CodeRabbit note that the Rivers assertion only checks for the absence of "Fill" (ribbon.rs:5303).
• The github-actions nit on the Symbology pane's "Color" label is addressed by this diff, which changes panes.rs:5213 to "Fill".
