Brand Guidelines
Everything you need to represent Testfly consistently.
Logo
Primary Logo
The Testfly logo combines a paper airplane icon with the wordmark. Always use the official logo file — never recreate or approximate it.
On light backgrounds
Use the standard logo on white or light surfaces.
On dark backgrounds
Invert the logo to white when placing on dark surfaces.
Clear space
Maintain a minimum clear space equal to the height of the airplane icon on all sides.
Minimum size
24px height — minimum
40px height — recommended
Never display the logo smaller than 24px in height to ensure legibility.
Don't
Rotate or skew the logo
Recolor the logo
Stretch or distort
Colors
Color Palette
Our palette is grounded in warm stone tones with a signature brand amber. Use sparingly for impact.

Primary actions
Use Brand 500–600 for CTAs, links, and interactive elements. Ensure WCAG AA contrast on white backgrounds.
Text & UI
Stone 900 for headings, Stone 600 for body text, Stone 400 for secondary text. Never use pure black (#000).
Accents
Brand 200–300 for subtle highlights, badges, and decorative elements. Reserve Brand 100 for backgrounds.
Typography

We use Inter as our primary typeface. It's clean, highly legible, and works well at every size.

Voice
Voice & Tone
We are
-
Direct. Lead with what the product does, not what it could do.
-
Technical. Our audience is developers. Speak their language.
-
Confident. We know what makes us different. Say it plainly.
We are not
-
Buzzwordy. No "revolutionize", "leverage", or "best-in-class".
-
Salesy. Show the terminal output. Let the product sell itself.
-
Vague. "pet.owner_id resolves to a real user" beats "data consistency".
