Ledger: Dark SaaS Dashboard Design System

Web · Dark · Minimal · SaaS · Finance

Ledger

A dense, dark interface for numbers, with a terminal-amber accent.

Ledger is built for screens full of numbers. It is dark first, compact and calm, like a trading terminal, with tabular figures in a monospace face and one amber accent for the active state and key values.

Do's and don'ts

Do set numbers in the monospace face with tabular figures.
Do keep amber for the one thing that matters on a screen.
Don't use more than three chart colors at once.
Don't add gradients or glow effects.
