| Accessibility | Spectrum’s color system is designed around visual perception, inclusive design, and accessibility. | The team describes accessibility work as continuous and iterative, and says using the system alone does not make a service accessible. |
| Components | Spectrum component pages include interactive playgrounds for exploring live components and their props and attributes. | It provides reusable interface components with usage guidance and coded examples. |
| Purpose | Spectrum is Adobe’s design system, described as a shared language that brings structure and connection across Adobe products. | The system helps teams make government services consistent with GOV.UK and learn from research and experience across service teams. |
| Support | Spectrum Hub offers contact options for feedback, bug reports, and general inquiries. | The team focuses support on central UK government digital services and says it cannot reliably provide guidance for different contexts. |

In their own words
Adobe Spectrum
Adobe Spectrum is Adobe’s design system, a shared foundation and language for creating experiences across Adobe products. It provides foundations, design tokens, patterns, components, and guidance intended to support consistent, flexible work. Component pages offer interactive playgrounds where users can explore live components and their properties; the playgrounds use component data connected to Spectrum repositories. Tokens capture reusable decisions about color, spacing, typography, motion, and sizing. Spectrum’s color guidance emphasizes accessibility, recommends meeting WCAG contrast minimums, and advises providing a label or icon so color is not the sole carrier of meaning. Typography guidance addresses consistent styles and behaviors, including text scaling with accessibility preferences on iOS and Android. Dedicated React and Web Components areas are available in beta; iOS, Android, and other platform areas are described as coming soon. Spectrum Hub provides foundational and implementation guidance, playgrounds, and contact options for feedback, bug reports, and inquiries. The September 2026 release describes the Hub as an initial release, with mobile documentation and unified experience guidance planned for later releases. Spectrum is listed as free and open source.
GOV.UK Design System
The GOV.UK Design System helps government teams build services with shared styles, reusable components and patterns for user-focused tasks. Its guidance covers page structure, typography, colour and images; components include coded examples, and patterns address particular tasks and page types. Published guidance includes details about user-research testing. Teams can add GOV.UK Frontend through npm or include compiled files. In production projects, components can be used as HTML or as Nunjucks macros when Frontend is installed with npm and the application uses Node.js. Prototyping requires GOV.UK Prototype Kit version 7 or later. The code is public under the MIT License, and the listed plan is free. The system aims for WCAG level AA compliance, but its use alone does not make a service accessible; component accessibility checks combine tools, automated deployment tests and manual testing. The Government Digital Service maintains the system, with a focus on central UK government digital services. Support may be limited for other contexts. Compiled files include all Frontend CSS and JavaScript, without selective component assets or a customizable build.
