Overview
Visual Theme & Atmosphere
Pennylane is an accounting and financial management platform for businesses and their accounting firms. Its careers page gives the scale: "Créée en 2020", €175 million raised through a Series E, 1,000 "Pennylaners" of 43 nationalities, and 6,000 accounting firms supporting more than 800,000 businesses that use Pennylane daily — in France and, since 2025, in Germany. The company is Pennylane SAS, head office 2-4 rue Jules Lefebvre, Paris.
The site is fresh and confident: a deep teal #003d3d for type and buttons, a flashy green
#00f872 accent, white and beige #f8f4f1 surfaces, and salmon, yellow and blue as
supporting colours. Everything is set in Manrope.
What makes it worth reading:
- One teal for text and action.
--color-pennylane,--color-primaryand--color-typoare all#003d3d. - A flashy green accent.
--color-pl-green-accent#00f872— used for highlights and for the label of the larger call to action on teal. - Hover as lift. The call to action keeps its colour, rises 2px and casts a shadow.
Primary tasks
- Start Pennylane or request a demo, by business type.
- Explore product, pricing and resources; sign in.
Brand Narrative
Pennylane, founded in 2020, brings businesses and their accountants onto one financial platform, and its site trades the usual finance blues for a deep teal and an electric green. Actions stay teal and respond by lifting rather than changing colour.
Principles
- Teal, not navy. One deep colour for text and action.
- Electric accent. Green for what should stand out.
- Lift to respond. Hover rises instead of recolouring.
Personas
Not researched. No persona claim is made from a UI capture.
Colors
Measured with getComputedStyle on pennylane.com/fr: 133 root custom properties — about 56
