Design System 3 by Sigma

A Figma‑based design system and UI kit that provides a cohesive visual language for product design workflows. It includes a set of carefully crafted components, a new color palette with light, dark, and “liquid glass” modes, and precisely modified typography to maintain rhythm across screens. The system leverages Figma’s latest standards, variables, auto‑layout and responsive features, allowing seamless switching between component modes and consistent appearance on mobile and desktop.

The package also supplies customizable documentation and a user‑journey template inspired by established design practices, aiming to streamline communication within design teams. Documentation is organized to guide the design process and to serve as a reference for the system’s principles, such as attention to detail, harmony, and consistency.

Targeted at product designers and design teams that work in Figma, it offers a ready‑to‑use, extensible foundation for building end‑to‑end experiences while supporting light/dark mode toggling and responsive layouts without additional configuration.
