Sigil’s
brand brief

Start with SIGIL. Remove the repeated I, then fit S, I, G and L into a square. The seal is the brand’s method applied to its own name.

SIGIL

Remove the repeated letter.

→

Press the four letters into one mark.

Give it space

Leave at least one-quarter of the seal’s width clear on every side.

Choose the right size

Use the dedicated favicon at 16 px. Below 24 px, use the small master. Keep the horizontal lockup at least 96 px wide on screen.

Keep the drawing intact

Do not stretch, rotate, outline or add shadows to the mark. Keep it off busy photographs.

The original brief records a resemblance review. That review is not trademark clearance.

Each typeface has a job. The display face gives Sigil its character; the reading and data faces keep the work usable.

Pale blue is the default ground. Klein blue gives larger brand moments their intensity. Dark text and quiet document surfaces make the details easy to read.

Keep orange out of the website. Reserve the lighter construction-line color, Struck, for guides and struck text, never body copy.

Write like a designer talking to a founder across a table. Explain the reason for a decision. Be candid about a problem without mocking the work.

These Sigil examples show how one identity changes across a public message, a private delivery and an image.

Imagery with a clear subject

The mark appears out in the world. A blue-hour sky, flash-lit foreground, wide-angle distortion and grain give the images a recognizable treatment.

Use the actual product when explaining what someone receives. Avoid decorative still lifes that need an explanation.

Motion with a purpose

Use a 200 ms transition for controls and an 800 ms press motion for expressive moments. Environmental video can loop: let flowers and clouds move while the mark stays clear. Include a pause control and a still image for reduced motion.
