OHQ wordmark
The everyday logo: the site header, footers and slides. In a lockup, “.ai” follows it in Martian Mono.
Brand
The OHQ brand.
OpenHQ is building a headquarters for agents, so the brand is drawn like one: letters as walls on a floor plan, in black, grey and white. Here are the marks, the colors and the type, and how to use them.
§ 01 · Name
Open is the mission. HQ is the vision.
We research and build open infrastructure for agents, to become the go-to headquarters for them. The name holds both, and the wordmark shows it: OPEN in grey, HQ in ink.
- OpenHQ
- The name. One word, with a capital O, H and Q.
- OHQ
- The short form, and the everyday wordmark.
- ohq.ai
- The domain. The OHQ wordmark carries “.ai” after it.
- Open HQ
- Not two words, and not OpenHq or Openhq.
OpenThe mission
HeadquartersThe vision
§ 02 · Logo
Letters drawn as walls.
The wordmark spells OHQ in walls on a 48-unit grid: an O that is a room with its door open, in grey for Open, then an H, and a Q whose wall opens at the corner and runs out past it. It's drawn, not typed, so use the files below rather than setting it in a font.
Full name
OpenHQ wordmark
The same walls with PEN added: OPEN in grey, HQ in ink. For where the full name belongs, such as a title page, the mission or the end of a talk. It takes no “.ai”.
Logomark
The O
The wordmark's O on its own: a room with its door open. Drawn in ink when it stands alone. For favicons, avatars and anywhere the wordmark would be under 16px tall.
Grid48 units tallLetters stand 42 units tall, from y=3 to y=45, and are 40 wide with 5 between them.
Walls6 unitsEach letter is one line drawn with a 6-unit stroke, so a wall is 2px at 16px tall.
Door10 units, in greyThe O for Open is a room with a gap in its bottom wall: the door, left open.
TailRuns to the edgeThe Q's tail goes out past the corner, so give it room and never crop it.
½
Clear space
Keep at least half the wordmark's height clear on every side. Nothing else goes in it, including the “.ai”, which sits outside it.
16px
Minimum size
Keep the wordmarks at least 16px tall, where a wall still draws 2px wide. Below that, use the O on its own.
Don't
Swap the tonesIn the wordmark the O is always the grey one. It's the Open in OpenHQ.
OHQ
Set it in a fontThe letters are drawn as walls. Use the SVG files.
Stretch, slant or rotate itThe walls stay square to the grid.
Put it on mid-greyThe O disappears. Use paper, white or ink behind it.
Product logos
AgentFGA
AgentFGA wordmark
The same walls: AGENT in grey and FGA in ink, as OPEN and HQ. The last A is the AgentFGA logomark, so only that A has feet. The everyday AgentFGA logo: the AgentFGA site's header and footer, title slides and the README.
AgentFGA logomark
The gate A
An A with its feet turned in and its crossbar in grey as a gate. For the favicon, avatars and anywhere the wordmark would be under 16px tall.
§ 03 · Color
Black, grey and white. No accent color.
Warm neutrals only. Emphasis comes from weight, fill and inversion, never from a hue. Grey is the second tone: it marks the secondary part of a mark, like the O for Open. Click a swatch to copy it.

§ 04 · Type
Three open-source typefaces.
All three are free under the SIL Open Font License and served from Google Fonts. Archivo is set wide and heavy for headlines, Public Sans carries the reading, and Martian Mono labels things.

§ 01 · Mission
§ 05 · Illustration
Built from blocks, in one projection.
Figures are isometric, all in the same projection as the wordmark building on the home page. White is what's already there, ink is what's ours or new, grey is what's still going up, and agents are small cubes with grey tops. One soft shadow sits under the ground.
01 · Foundation
Ink marks what we build: the open infrastructure, poured as the foundation, with the grey columns started.
02 · Built on top
Once something's built on it, the foundation turns white and the new work is in ink. The door stands open, and agents walk in.
WhiteWhat's already there, or someone else's.

§ 06 · Writing
Plain, specific and measured.
We write the way we build: in the open, with the evidence attached. Say what something does and who it's for, in the words an engineer would use.
