Realtime Colors
Visualize color palettes and fonts on a real website mockup in real time
About Realtime Colors
Realtime Colors is a free web-based tool that lets designers and developers visualize color palettes applied to a realistic website layout in real time. Instead of guessing how colors will look together, you pick your text, background, primary, secondary, and accent colors and instantly see them distributed across a full page mockup with hero sections, content blocks, cards, and buttons. The tool also handles font pairing with a built-in type scale system, includes a contrast checker for WCAG accessibility compliance, and exports palettes in multiple formats including CSS, Tailwind CSS, SCSS, and framework-specific presets for shadcn, DaisyUI, NextUI, Bootstrap, Material UI, and Chakra UI. Color scheme generation supports complementary, analogous, triadic, and other mathematical approaches, plus a randomize function with color locking to explore variations quickly.
Key Features
Live Website Mockup Preview
See your chosen colors applied across a realistic website layout with hero sections, content blocks, cards, buttons, links, and navigation in real time as you adjust.
Five-Color System
Assign colors to five semantic roles — text, background, primary, secondary, and accent — and watch them distributed across all UI elements automatically.
WCAG Contrast Checker
Built-in contrast ratio checker displays color-coded indicators for AA and AAA accessibility standards, helping ensure your palette meets web accessibility guidelines.
Font Pairing & Type Scale
Select and preview fonts alongside your color palette with a configurable type scale system. Supports font randomization, locking, and export of font sizes in REM.
Color Scheme Generation
Generate palette suggestions using mathematical color relationships including complementary, analogous, triadic, split-complementary, and shade-based schemes.
Multi-Format Export
Export palettes in CSS, Tailwind CSS, SCSS, ZIP, PNG, and QR code formats. Color values available in HEX, RGB, HSL, OKLAB, and OKLCH with optional shade generation.
Framework Presets
One-click export presets for popular UI libraries and frameworks including shadcn, DaisyUI, NextUI, Bootstrap, Material UI, and Chakra UI.
Color Locking & Randomization
Lock specific colors in your palette while randomizing others to quickly explore variations and find the perfect combination.
Figma Plugin
Use Realtime Colors directly within Figma to apply and test color palettes on your designs without leaving your design workflow.
