Lobbyface brand

Warm paper, deep ink, one signal.

Lobbyface sells a face that represents a business. The brand looks like the businesses we serve want to look: calm, precise and human. Most of every screen is paper and ink; the signal colour marks what is alive.

01Logo

A doorway and a person.

The mark is an arch, the entrance to a lobby, with a person inside it: the head in the signal colour, the shoulders cut out of the arch. The wordmark is Instrument Sans SemiBold in lower case, slightly tightened, drawn as outlines.

App icon
Clear space

Keep clear space of at least one head diameter (the signal circle) on every side of the logo.

Minimum size

Lockup 20 px tall on screen. Mark alone 16 px; below that, use the app icon.

Don’t

Recolour the head, stretch, add shadows or gradients, set the wordmark in another font, or put the logo on photos without an ink or paper panel.

02Colour

Mostly paper. Sometimes ink.

Paper is the page; ink is text, primary buttons and the dark sections that hold 3D. Signal is used sparingly: the head in the mark, live states, one highlight per view. On paper, accent text uses Signal Ink, which passes contrast.

03Typography

Three voices, one page.

Instrument Sans carries everything. Instrument Serif italic marks the one or two words of a heading that matter most. JetBrains Mono labels, indexes and data, like the lip sync readout.

04Components

Few parts, used the same way.

Buttons are pills with an arrow that moves on hover. Cards have an 18 px radius and a 1 px border on paper, none on ink. Sections open with a mono index, a short rule and a label.

Of course. Shall I request it for you?

053D

3D proves, it doesn’t decorate.

Our 3D objects are the product working: Riya's real face, scanned into lines and moved by our own lip sync network. One 3D object per view, always on ink, points in paper, signal only where something moves. It pauses off screen and holds still for people who prefer reduced motion.

Imagery

Real screenshots of hosts we built, never stock photos of people or robots. Crop in on the host; keep the interface visible.

Motion

Content fades up 14 px over 700 ms once, as it enters. The 3D face follows the pointer gently. Nothing loops except live states.

Layout

A 1200 px grid of 12 columns, 20–32 px gutters, generous vertical space (96–128 px per section). Headings left-aligned.
