UI Design Agency London

Component library design

Every project ships with a Figma component library that engineering builds against. Components carry properties, variants, states and documentation. The library is the single source of truth for design and development. One-off screens are avoided where the system can carry the work.

• Figma library with variant components
• Auto layout and constraints throughout
• Component documentation in-file
• Library handoff to engineering

Brand-led visual systems

UI design is the place where brand becomes interface. We translate brand identity (logo, voice, colour, type, photography) into a digital system that feels like the brand in every interaction. Brand integrity preserved at every viewport.

• Brand identity translation to digital
• Voice and tone reflected in copy patterns
• Photography and illustration direction
• Motion principles per brand

Type and colour systems

Type and colour are the load-bearing visual choices. We define type scales, weight roles and line-height rules. Colour scales include base, surface, accent and semantic colours, all WCAG-checked for contrast. Light and dark mode planned together, not bolted on later.

• Type scale and weight role documentation
• Colour scale with WCAG contrast checks
• Light and dark mode pairing per token
• Tokens exportable to Tailwind or CSS custom properties

Light and dark mode

Dark mode is no longer optional. We design both modes from day one with paired colour tokens so neither feels like an afterthought. Image and chart styles reviewed for both modes. User preference detection via prefers-color-scheme and a manual toggle.

• Paired light and dark tokens
• Image and chart treatment per mode
• prefers-color-scheme and manual toggle
• Accessibility re-checked per mode

Icon and illustration systems

Icons and illustrations are a brand surface that scales across the site. We design custom icon sets where the brand justifies it (or use lucide where it does not) and produce illustration systems with consistent style, weight and palette. Documentation included.

• Custom icon set or lucide adoption
• Illustration style guide
• Sizing and stroke rules
• Export and integration with the component library

Design system documentation

A design system without documentation is a Figma file nobody can use. We document component anatomy, props, states, do-and-do-nots, voice rules and motion principles. Documentation lives alongside the library and updates with every release.

• Component anatomy documentation
• Do-and-do-not examples per component
• Voice and motion principles
• Living documentation, not a one-off PDF
