Lumbridge brand mark

Concept

Lumbridge's symbol is an original ember-flame wrapped around a bridge arch. The diagonal negative space also reads as a terminal chevron or an open gateway. Together, those shapes express a fast native workspace where engineers cross between terminals, tools, hosts, and agents.

The mark is symbol-only. Do not ship a Unicode fire emoji as the application icon, add pseudo-medieval ornament, or attach generated lettering to the mark.

Color

Role	Hex	Intended surface
Ember	#FF6B35	Canonical application icon and neutral contexts
Ember, light UI	#D94824	Light surfaces around #F6F3EE
Ember, dark UI	#FF8A5B	Dark surfaces around #0B0F14

All files have transparent backgrounds. The surface colors above are usage guidance and are not baked into the assets. Do not add gradients, drop shadows, outlines, or extra flame colors.

Assets

The 1024 px master is assets/brand/master/lumbridge-mark-master-1024.png. Use it as the source for new platform exports.

• assets/brand/app-icons/lumbridge-app-{size}.png contains the canonical Ember icon at 16, 32, 48, 64, 128, 256, 512, and 1024 px.
• assets/brand/light/lumbridge-mark-light-{size}.png contains the light-UI colorway at the same sizes.
• assets/brand/dark/lumbridge-mark-dark-{size}.png contains the dark-UI colorway at the same sizes.

The existing PNGs are RGBA and square. Packaging may derive platform-native containers such as macOS .icns later, but those derived files should preserve the supplied canvas and must not stretch or crop the symbol.

Placement

• Preserve the mark's aspect ratio and transparent canvas.
• Outside an application-icon tile, keep clear space equal to at least one eighth of the rendered mark height on every side.
• Prefer the prepared export nearest the requested display size. Do not scale a 16 px export upward.
• At 16–24 px, use the canonical app-icon export without a wordmark, badge, or status dot. The flame and gateway are the intended small-size reading; the terminal chevron becomes secondary.
• Do not place detailed artwork or low-contrast orange immediately behind the transparent mark.

Generation and production record

The concept was generated once with the built-in image_gen mode using this prompt:

Use case: logo-brand. Asset type: native desktop application icon master for Lumbridge, a very high-performance Rust terminal multiplexer and AI-agent workspace. Create one original symbol-only brand mark that expresses firemaking energy, a bridge or gateway, and a terminal prompt through a single strong silhouette. Use a compact upright ember-flame whose interior negative space forms a clean bridge arch or open gateway; incorporate one extremely subtle angular terminal chevron idea into the geometry without adding a separate floating glyph. Use a vector-friendly, flat, minimal geometric mark with precise edges, centered on a square transparent canvas. Use warm ember orange. Exactly one symbol; no text, letters, wordmark, emoji glyph, gradient, shadow, 3D, mockup, border tile, or watermark. Avoid RuneScape imagery or style, game trademarks, medieval crests, literal campfires, logs, swords, shields, runes, detailed sparks, characters, mascots, and decorative flourishes.

The selected output's geometry was retained. Production exports were then made deterministically: low-alpha detached pixels were removed, the mark was inset onto a 1024 px transparent canvas, its generated shading was replaced with the three exact flat colors above, and Lanczos downscales were produced. No third-party artwork, typeface, or game asset is included.

Originality and release constraints

This identity deliberately uses only generic fire, bridge, gateway, and terminal ideas. Do not adapt or add artwork, interfaces, names, symbols, screenshots, or other assets from RuneScape or another game.

Generation and internal review are not a trademark search or legal clearance. Before a public release, perform a similarity search for the symbol and obtain product-name/trademark review; the original mark does not by itself clear the name Lumbridge. Keep the prompt and this production record with the assets for provenance, and review the image-generation provider's then-current output terms before redistribution.
