Nebula App Icon

The rounded, asymmetric symbol and cutout prompt are shared by 25 colorways. Titanium (palette 21) is the default application and README identity. The display name is Pebrel; asset paths retain Nebula for compatibility. The original 01–24 palettes are available as personal choices, with graphite violet retained as palette 25.

Setting	Source	Role
titanium	nebula-titanium.svg	Default identity; palette 21
silver-violet	nebula-light.svg	Optional silver-violet colorway; palette 12
graphite-violet	nebula-dark.svg	Optional graphite / gray-violet colorway; palette 25

nebula_settings/src/app_icon.rs is the canonical catalog of stable setting keys, original palette numbers, bilingual names and colors. The renderer exports icon-catalog.json from it. Personal color options do not imply exclusive colors or completed trademark clearance.

Switching

GPUI Settings → Appearance → App icon writes app_icon= to nebula_settings.txt. Missing or invalid values fall back to Titanium. Existing valid selections remain unchanged. The picker initially shows the three colorways above and the current selection, with a button to show all 25. Appearance reset restores the default; appearance backup includes the selection. Icon selection is independent of terminal/system theme selection.

On Windows, selection updates open window icons (including Alt+Tab), the tray, and in-app previews. New windows and subsequent notifications use the selection too. Window icons use per-window DPI and are reapplied when the window's scale changes. Existing pinned shortcuts, Explorer's EXE icon and the installer keep the default brand icon; no shortcut, executable or system icon cache is rewritten. Linux/macOS currently change only the in-app preview; their Dock/launcher icon remains the packaged default.

Clarity and resource budget

The default ICO contains 32-bit RGBA PNG frames at 16, 20, 24, 28, 32, 40, 48, 56, 64, 80, 96, 112, 128 and 256 physical pixels. The shared coverage atlas contains these sizes plus a 512px frame. Below 64px, the mark gradually increases from 90 to 108 SVG units, with a pixel-fitted prompt and a minimum 1.5px cutout stroke. The underline is aligned to the physical pixel grid. The tile and outer symbol paths stay unchanged; 64px and larger preserve the original master geometry.

The generator renders at 8× resolution for 16–64px and 4× above that, then averages premultiplied coverage before applying colors. This avoids colored transparent fringes and sharpening halos. Nonstandard sizes resample coverage with a non-ringing triangle filter before colorization. In-app previews request their actual logical size times the window scale factor; the tray receives exact-size RGBA pixels without a second resize. Antialiasing still produces partially covered edge pixels, and shell/browser scaling can affect appearance.

Windows embeds one default icon group and one shared coverage atlas, not 25 complete ICOs or PNG collections. Palette colors are applied at runtime using the existing image dependency. Non-Windows in-app previews use the same atlas. The combined Windows image payload is 80,402 bytes (78.52 KiB), below the 96 KiB budget enforced by the generator and tests. This measures image data, not installer growth. PNG/preview caches have a 128-entry limit; native window icon handles are reused, and owned tray handles are destroyed when replaced.

nebula.ico is byte-identical to nebula-titanium.ico, and nebula.png to nebula-titanium.png. Alternate ICOs and 1024px PNG exports are design assets, not extra GPUI runtime embeds.

Regenerate using Node.js 24+ with @resvg/resvg-js (verified with 2.6.2):

node scripts/render-app-icons.mjs /path/to/renderer/package.json
node scripts/render-app-icons.mjs /path/to/renderer/package.json --check
python3 -m unittest scripts.tests.test_app_icons -v
cargo test -p nebula-settings --offline --locked
cargo test -p nebula --bin nebula --features gpui-shell app_icon::tests

The renderer is development-only; it adds no application dependency. The optional argument locates a separate renderer installation. The default nebula.ico and nebula.png exports always remain Titanium.

Design archive

The local 24-color exploration remains in docs/design/icon-color-lab-2026-09-05/index.html. The updated local preview at docs/design/icon-all-palettes-2026-09-05/index.html shows all 25 choices on light/dark surfaces and a before/after small-size comparison. These are PNG contact sheets, not native taskbar screenshots. Original sage SVG masters remain in docs/design/icon-final-2026-09-05/archive/. The historical pages do not define the current default. These local design archives are ignored by Git and are not required by the asset tests.

Third-Party Logo Assets

Agents settings vectors

The Agents settings page renders 24 logical pixel SVG marks rather than enlarging the sidebar PNG textures. Claude, Kimi and Oh My Pi reuse the SVG sources below; Cursor and Copilot reuse the existing settings icons. OpenAI, OpenCode, Pi and Grok use nebula_app/assets/icons/nebula-agent-{openai,opencode,pi,grok}.svg, retrieved from the fixed npm package @lobehub/icons-static-svg 1.95.0: https://unpkg.com/@lobehub/icons-static-svg@1.95.0/icons/{name}.svg. These four sources are unchanged except for a final newline, under the collection's MIT license. Product trademarks belong to their owners. GPUI renders the SVG alpha masks using theme ink, with orange for Claude and purple for Oh My Pi; sidebar PNG presentation is independent.

Cursor and GitHub Copilot settings icons

nebula_app/assets/icons/nebula-agent-cursor.svg and nebula_app/assets/icons/nebula-agent-copilot.svg use the monochrome marks from @lobehub/icons-static-svg 1.95.0, retrieved on 2026-09-20:

• Cursor: https://cdn.jsdelivr.net/npm/@lobehub/icons-static-svg@1.95.0/icons/cursor.svg
• GitHub Copilot: https://cdn.jsdelivr.net/npm/@lobehub/icons-static-svg@1.95.0/icons/githubcopilot.svg
• License: MIT, copyright LobeHub.

Only the unused title, CSS sizing attributes and explicit closing path tags were removed. The viewBox and path geometry are unchanged. The two embedded SVGs total 2,393 bytes; the other settings icons reuse the sidebar's existing small textures. These marks identify the installed tools and do not imply endorsement.

Claude Code and Trae CLI

ai_claude.svg and ai_trae.svg are vector masters from LobeHub's icon collection, retrieved on 2026-09-13 at these exact revisions:

• Claude: https://github.com/lobehub/lobe-icons/blob/f25f22c0e7295a76077fe417d23deeb56eefdf3e/packages/static-svg/icons/claude-color.svg
• Trae: https://github.com/lobehub/lobe-icons/blob/0935313ef153c255958754d9d2523862e069c2c9/packages/static-svg/icons/trae-color.svg
• Collection license: MIT, copyright LobeHub. Product names and trademarks remain with their respective owners; use identifies running programs and does not imply endorsement.

The matching PNGs are 1024 x 1024 transparent exports made with @resvg/resvg-js 2.6.2 and fitTo: { mode: 'width', value: 1024 }, without changing geometry or colors. The renderer is a development tool, not a product dependency. Both shells prepare antialiased textures at the requested physical size and keep the source colors on light and dark themes.

Trae's trae-cli executable name is declared by ByteDance's trae-agent project under [project.scripts]. Detection and branding do not imply Hook, cold-start, resume, or fork support.

CodeBuddy Code

ai_codebuddy.svg contains the CodeBuddy color mark from LobeHub's icon collection, with only a final newline added. It was retrieved on 2026-09-14 at the following exact revision:

• Source: https://github.com/lobehub/lobe-icons/blob/3928068a986819bedd4feca1a01a9ba9c3229f3b/packages/static-svg/icons/codebuddy-color.svg

ai_codebuddy.png is a 1024 x 1024 export made with @resvg/resvg-js 2.6.2 and the same rendering settings as Claude and Trae above. Both shells preserve its colors on light and dark themes.

The codebuddy, cbc, codebuddy-code, and codebuddy-lowmem aliases are published in @tencent-ai/codebuddy-code 2.150.0. The cbc-prewarm helper is excluded. Recognition does not add session resume, fork commands, or AI hooks.

Kimi Code

ai_kimi.svg contains the Kimi color mark from LobeHub's icon collection, with only a final newline added. It was retrieved on 2026-09-17 from the published npm package @lobehub/icons-static-svg 1.95.0 (icons/kimi-color.svg), the packaged form of the lobe-icons repository's packages/static-svg directory (the same artwork ships as the Kimi.Color component in @lobehub/icons 5.18.0):

• Collection license: MIT, copyright LobeHub. Product names and trademarks remain with their respective owners; use identifies running programs and does not imply endorsement.
• PNG SHA-256: FC3F905ADC68DFE9E14AD23B123F55AB71D32BF0D855A2CF6580F6B5CFF0BE99

ai_kimi.png is a 1024 x 1024 transparent export made with @resvg/resvg-js 2.6.2 and the same rendering settings as Claude and Trae above. The mark is a white letterform with a blue accent; embedded unchanged it would vanish on light surfaces, so both shells treat it as a luminance map at render time (like OpenCode): the letterform takes the theme ink at full strength and the accent dims proportionally. The committed bytes keep the source colors. The icon identifies running kimi and kimi-code processes and does not imply endorsement by Moonshot AI.

Oh My Pi

ai_omp.svg is a Pebrel-drawn purple gradient π mark following the maintainer's 2026-09-13 visual reference. Its simple vector geometry is authored here; no third-party application asset is embedded. This is a presentation variant, not the upstream white π / orange connector artwork currently published in oh-my-pi/assets/icon.svg. ai_omp.png is a transparent 1024 x 1024 export made with the same resvg settings as Claude and Trae above. It identifies the existing omp / oh-my-pi agent identity and preserves its gradient in both themes.

Grok

ai_grok_dark.png and ai_grok_light.png are unmodified copies of Grok_Logomark_Dark.png and Grok_Logomark_Light.png from the official xAI asset archive:

• Brand guidelines: https://x.ai/legal/brand-guidelines

xAI owns the trademark, intellectual property, and branding rights in xAI, Grok, and their logos. The xAI Brand Guidelines are usage terms, not an open-source asset license. These files are used only to identify a running grok or grok-cli process and do not imply xAI endorsement, approval, or sponsorship. The application selects the supplied dark or light file for contrast and scales it only when rendering; the committed files are unchanged.

Google Antigravity

ai_antigravity.png is an unmodified copy of the full-color product icon from Google's Antigravity press assets, verified on 2026-09-06:

• Press assets: https://antigravity.google/press/
• PNG: https://antigravity.google/assets/image/brand/antigravity-icon__full-color.png
• Dimensions: 540 x 540, with transparency
• SHA-256: E0CD08CCD10CD8D08CCF0BA449823EE88495825C0841619618100D3AB089F51E

Google retains rights to its product names and logos. Publication in a press kit does not make the logo an open-source asset or imply endorsement. The icon is used to identify running antigravity, antigravity-cli and agy processes. Both UI shells keep its original colors on light and dark themes and resize it only for rendering. No LobeHub asset is embedded for Antigravity.
