> Teal and White Ledger. A clear, high-contrast digital ledger laid out on a clean white page, highlighted by a single, prominent teal ink.

**Theme:** light

**Site:** https://n26.com

N26 employs a utilitarian, almost institutional aesthetic, built around a dominant teal that provides a singular brand anchor against an otherwise stark monochrome palette. The design emphasizes functional clarity, using crisp lines and generous whitespace to present complex financial information in an accessible manner. The restricted use of color focuses attention on key interactive elements and a distinct brand presence, avoiding visual clutter.

## Layout

The page adheres to a max-width centered content model, creating visual stability. The header floats at the top, consistent across different content. The hero section is full-bleed 'Deep Teal' with a prominent centered headline and descriptive text, followed by the primary CTA. Content sections follow a vertical rhythm with generous spacing. Information is presented in clear, distinct blocks, often utilizing a multi-column grid for features or data like the 'Risk Indicator' modules. The layout is spacious with strong visual separation between content blocks.

## Imagery

The site's visual language is dominated by UI elements and product-focused graphics. Photography is absent, replaced by crisp product screenshots or abstract, clean graphics to illustrate financial concepts. Icons are filled, monochrome, matching the 'Ink Black' text where 'Deep Teal' is the primary background. Imagery is primarily explanatory and functional, contained within clear sections, avoiding full-bleed or overlapping styles. The density is moderate, allowing text to remain dominant while visuals support key messages.

## Guidelines

### Do

- Use 'Deep Teal' (#088177) exclusively for primary calls-to-action and key branding in hero sections.
- Maintain high contrast text with 'Ink Black' (#1b1b1b) on 'Arctic White' (#ffffff) backgrounds for all body and heading content.
- Apply 'Horizon Gray' (#e9e9e9) for subtle UI borders and dividers to structure content without heavy lines.
- Structure display headings with 'N26-Extended' font family, using weights 400 or 500 for impact.
- Utilize 'Arctic White' (#ffffff) for page backgrounds and elevated card surfaces, creating a clean canvas.
- Apply a 6px border-radius for all primary and secondary buttons, balancing softness with a structured look.

### Don't

- Do not introduce additional saturated colors beyond 'Deep Teal' for primary interactive elements; color saturation is highly restrained.
- Avoid applying heavy shadows or complex gradients; the system relies on flat colors and distinct borders for depth.
- Do not deviate from the specified tight letter-spacing for 'N26' font at smaller sizes, as it's critical for text clarity.
- Avoid using 'N26-Extended' font for body copy or small text; it is reserved for headlines.
- Do not use different radius values for buttons and input fields; consistently apply 6px for buttons and 4px for inputs.
- Do not use highly decorative imagery; illustrations and photos should be either product-focused or abstract and minimal.
