Converly Colors: Free Color Palette Generator for Modern Design Systems

Converly Colors is a free, browser-based color palette generator created by Converly, an AI consulting and implementation company based in Barcelona, Spain. It helps designers, front-end developers, product teams, and founders build consistent color systems with light and dark modes, 12-step tonal scales, CSS variables, and a Design.md export for AI coding tools.

The tool provides a structured color foundation that both developers and AI assistants can use to create consistent, accessible, and well-documented product interfaces.

What Is Converly Colors and How Does It Work?

Converly Colors transforms one or more brand colors into a complete color system for websites, applications, and digital products. Users select their base colors, review the generated palette, preview light and dark themes, and export the results for development.

Generate Custom Color Palettes From Brand Colors

Users can start with a single base color or multiple brand colors. The palette engine generates coordinated shades that can be used across backgrounds, surfaces, text, borders, and interactive components.

Create Production-Ready Color Systems

The generated palette organizes colors into defined tonal steps, helping teams choose appropriate shades for buttons, cards, borders, focus rings, and other interface elements.

Build Consistent Design Tokens

A structured color system provides a common foundation for designers and developers. Instead of choosing individual hexadecimal values for every component, teams can use consistent color tokens throughout a product.

Key Features of Converly Colors

Converly Colors combines palette generation, theme previews, developer-friendly exports, and AI-oriented design documentation in one browser-based tool.

Generate 12-Step Color Scales

Each generated color includes a 12-step tonal scale, ranging from light tints suitable for backgrounds to deeper shades for text, borders, and interactive states.

These steps help organize colors according to their intended roles within a design system.

Generate Light and Dark Mode Color Palettes

Converly Colors creates matching light and dark variants for its color scales. Rather than simply inverting colors, the goal is to preserve the intended role of each shade across both themes.

Designers can preview both modes side by side and refine the base colors to suit their brand.

Export CSS Variables for Developers

Once a palette is ready, users can export it as CSS custom properties. These variables can be added to global stylesheets, component libraries, or frameworks that support CSS variables.

Predictable naming makes it easier to reference individual color steps and maintain consistent theming throughout an application.

Export Design.md for AI Coding Tools

Design.md is a distinctive feature of Converly Colors. It documents the generated palette in Markdown, including color scales, intended usage, light and dark modes, and variables for backgrounds, surfaces, borders, text, and accents.

Developers can add this file to a project repository to give AI coding assistants and agents a documented source of truth for the product's color system.

Design.md: Connect Design Systems With AI-Assisted Development

AI coding tools can produce more consistent interfaces when they have clear project documentation and design constraints. Converly Colors uses Design.md to communicate color decisions in a format that developers and AI assistants can read.

Give AI Coding Assistants Clear Color Guidelines

The exported documentation describes the available color tokens and their intended roles. This helps provide context when AI tools generate components, pages, and styling code.

Reduce Inconsistent Colors in AI-Generated Interfaces

By documenting approved color variables, teams can guide AI-assisted development away from arbitrary hexadecimal values and inconsistent shades.

Maintain Design Documentation in Git Repositories

Because Design.md is a plain Markdown file, teams can commit it to GitHub or another repository, review changes through pull requests, and update it as the design system evolves.

CSS Variables and Framework Integration

Converly Colors generates CSS variables that can be incorporated into modern web development workflows.

Use Generated Colors With HTML and CSS

Developers working with plain HTML and CSS can add the exported variables to their stylesheets and reuse them across interface components.

Integrate Color Tokens With React, Vue, and Svelte

The generated CSS variables can be used in applications built with React, Vue, and Svelte, provided the project supports CSS custom properties.

Use Converly Colors With Next.js and Astro

Developers can incorporate generated color tokens into Next.js and Astro projects to maintain consistent branding across pages and components.

Support Tailwind CSS and Component Libraries

The exported values can also be adapted for Tailwind CSS configuration layers and component libraries, allowing teams to reuse their palette across different parts of a product.

Who Should Use Converly Colors?

Common Use Cases for Converly Colors

The tool can support several practical design and development workflows.

Create a Color Palette for a New Website

Generate a palette based on brand colors and apply the resulting variables to website backgrounds, buttons, typography, and other components.

Build Dark Mode for an Existing Application

Use the generated light and dark variants as a starting point for a consistent theme across different viewing preferences.

Refactor Inconsistent CSS Colors

Replace scattered, one-off color values with reusable CSS variables to make stylesheets easier to maintain.

Prepare Color Tokens for Component Libraries

Use the tonal scales as a foundation for defining consistent colors across reusable UI components.

Document Design Decisions for Distributed Teams

Share CSS variables and Design.md documentation so designers, developers, and collaborators can work from the same color specifications.

Maintain Consistent Branding Across Digital Products

Reuse the same color tokens across landing pages, dashboards, email templates, and internal tools where the relevant styling environment supports them.

How to Use Converly Colors

Converly Colors offers a lightweight browser-based workflow without requiring a software installation.

Step 1: Choose Your Brand Colors

Open the tool and select one or more base colors that represent your brand or product.

Step 2: Review the Generated Color Scales

Inspect the 12-step tonal scales and evaluate how the shades can be used for backgrounds, surfaces, borders, text, and interactive elements.

Step 3: Preview Light and Dark Modes

Compare both themes and refine the base colors until the palette aligns with the intended visual direction.

Step 4: Export CSS Variables

Copy the generated CSS custom properties into your project's stylesheet or adapt them to your preferred framework.

Step 5: Export Design.md for AI Development

Download the Markdown documentation and add it to your project repository so compatible AI coding tools can use it as design context.

Step 6: Maintain the Color System Over Time

Version the exported files and update them when your brand, interface, or design requirements change.

Color Accessibility and Design Consistency

A well-organized color system supports more consistent interface design and makes it easier to evaluate color combinations.

Choose Appropriate Background and Text Colors

The 12-step scales provide a structured set of shades for selecting foreground and background combinations. Developers should still test the actual combinations to verify that they meet applicable contrast requirements.

Maintain Consistent Colors Across Light and Dark Themes

Organized theme variants help teams preserve the intended visual hierarchy across different display modes.

Reduce Visual Inconsistencies and Maintenance Work

Documented CSS variables reduce reliance on ad hoc color values, making future design changes and theme updates easier to manage.

Accessibility note: Generated palettes should not automatically be assumed to meet WCAG contrast requirements. Check relevant text, component, and focus-indicator combinations before releasing a product.
