Color Token Cascade Generator

Turn one primary hex color into a full design-token cascade with primary, accent, neutral, semantic tokens, CSS variables, and Style Dictionary JSON

Paste a primary hex color and the generator will derive a design-token system that feels ready for a UI kit or design system handoff.

How to use it:

  • Primary Hex: the brand or core interface color
  • Accent Strategy: choose how the supporting accent hue is derived
  • Include Neutral Scale: add grayscale-like tokens for text, surfaces, and borders

What it outputs:

  • primary-50 through primary-900
  • accent-50 through accent-900
  • optional neutral-50 through neutral-900
  • semantic tokens such as primary, text-muted, bg-canvas, and border-subtle
  • CSS variables and Style Dictionary JSON

Overview

The Color Token Cascade Generator transforms a single primary hex color into a comprehensive design system palette, including primary, accent, and neutral scales. It automatically derives semantic tokens and exports production-ready CSS variables and Style Dictionary JSON to streamline the handoff between design and development.

When to Use

  • •When building a new design system and needing a consistent color ladder from a single brand color.
  • •When developers need to quickly generate CSS variables or Style Dictionary JSON for a UI kit.
  • •When creating accessible semantic tokens like text-muted or bg-canvas based on a primary brand identity.

How It Works

  • •Enter a primary hex code to serve as the foundation for your brand's color system.
  • •Select an accent strategy, such as complementary or analogous, to automatically generate supporting hues.
  • •Toggle the neutral scale option to include grayscale-like tokens for surfaces, borders, and typography.
  • •Export the resulting scales and semantic tokens as CSS variables or Style Dictionary JSON for immediate implementation.

Use Cases

Generating a full color palette for a SaaS dashboard from a single brand blue.
Creating a Style Dictionary JSON file for cross-platform design token management.
Rapidly prototyping a UI kit with consistent semantic naming conventions for borders and backgrounds.

Examples

1. SaaS Brand Identity Expansion

UI Designer
Background
A designer has a single brand color (#3b82f6) and needs a full set of UI tokens for a new web application.
Problem
Manually calculating 10 shades for primary, accent, and neutral colors is time-consuming and prone to inconsistency.
How to Use
Input #3b82f6 as the Primary Hex, select 'complementary' for the accent strategy, and check the neutral scale box.
Example Config
primaryHex: '#3b82f6', accentStrategy: 'complementary', includeNeutralScale: true
Outcome
A complete set of primary-50 to 900, accent-50 to 900, and neutral tokens ready for CSS implementation.

2. Developer Handoff for Design Systems

Frontend Developer
Background
A developer needs to implement a design system using Style Dictionary but only has the core brand hex.
Problem
Converting hex codes into a structured JSON format compatible with Style Dictionary is tedious.
How to Use
Paste the brand hex, choose an 'analogous' strategy for subtle accents, and generate the Style Dictionary JSON output.
Example Config
primaryHex: '#10b981', accentStrategy: 'analogous', includeNeutralScale: false
Outcome
A structured Style Dictionary JSON file containing primary and analogous color ladders for automated build pipelines.

FAQ

What export formats are supported?

The tool generates CSS variables and Style Dictionary JSON for design system integration.

Can I generate neutral colors?

Yes, by enabling the 'Include Neutral Scale' option, the tool creates a grayscale-like ladder for UI elements.

What is an accent strategy?

It determines how supporting colors are derived from your primary hex, using methods like complementary or analogous logic.

Does it generate semantic tokens?

Yes, it outputs tokens like text-muted, bg-canvas, and border-subtle based on the generated scales.

What color ranges are produced?

It generates a full ladder from 50 to 900 for primary, accent, and neutral scales.
