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.

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.
