The mark, the wordmark, and the green.

Everything below is cleared for press, partners, conference programs and event signage. Use the files as they are, without redrawing or recolouring them. The mark is a front view of the glasses; the dot on the left hinge is the eye-level camera.

Primary

The horizontal lockup.

The default. Use it everywhere unless the space is squarer than it is wide.

Secondary

Stacked, mark, wordmark.

For when the horizontal lockup will not fit: a square sponsor slot, a narrow column, a profile photo, or a case where the name already sits beside the logo.

Clear space

Give it room to breathe.

Keep free space around the logo equal to the height of one lens. Nothing crosses into it: no rules, no other logos, no photo edges, no text.

Minimum sizes: 24 px tall on screen for the horizontal lockup, 16 px for the mark alone. In print, 20 mm and 8 mm wide respectively.

Color

One green, and two neutrals.

The display emits a single wavelength, so the brand carries a single color. Signal Green is that wavelength. It is never a background for body text, and it never appears twice in the same element.

Display rules

Four rules every frame obeys.

These govern any image or animation showing what the wearer sees. They are optical constraints before they are style choices, which is why we hold to them in marketing as well as in the hardware.

The four laws
  • One color. A single green channel, projected into one eye. Never full color, never two eyes.
  • Light adds, it never blocks. The display can only brighten what is behind it. Nothing is ever occluded.
  • Thin strokes, soft bloom. Hairline weights with a gentle glow. No solid fills, no drop shadows.
  • Nothing near the edge. Content stays well inside the eyebox. No readout touches the frame.
Typography

Three typefaces, all free.

AaInter Tight · headlines and display. Bold, tight tracking, never lighter than 600.
AaInter · body copy and interface text.
AaSpline Sans Mono · eyebrows, labels, readouts and any figure that has to line up.

All three are on Google Fonts. The wordmark is drawn as outlines, so it needs no font installed anywhere.

Naming and usage

Two short lists.

Please do
  • Write Theora in running text, capital T only. THEORA in caps belongs inside the logo.
  • The product is Theora Lite. The runtime inside it is FERAL, always all caps.
  • THEORA OS is the name for that runtime in the Theora Pro programme, once it is orchestrating more than one device. Both are all caps. Do not use them interchangeably in the same sentence.
  • Use the SVG wherever the medium supports it. It stays sharp at any size.
  • Pick the light version on dark backgrounds and the dark version on light ones.
  • Drop to mono for one-color printing, embroidery and etching.
  • Place the logo on a plain area of a photo, never over a busy patch.
Please do not
  • Write TheOra, Theora.ai or Theora AI.
  • Recolour the mark, or add gradients, shadows, outlines or bevels.
  • Stretch, squash, rotate or skew any part of it.
  • Rebuild the wordmark in another typeface, or put a crossbar on the A.
  • Rearrange the lockup, or swap a different symbol in beside the wordmark.
  • Box the logo in, or set it below the minimum sizes above.

One-line description, if you need one: Theora makes agentic health glasses, powered by FERAL, a private local-first AI runtime.
