EEEgoCX (Custom eXperience) / Kolora

Kolora is a professional color palette generator that lives entirely in your browser. Explore complementary, analogous, triadic, tetradic, split complementary, and monochromatic harmonies for any base color. Save your favorite swatches, organize them into projects, and export your work as .kolora-project files. Privacy‑first, no accounts, no cloud.

How Kolora Works

Kolora is a fully client‑side color palette generator and project manager. It uses chroma.js for precise color conversions and harmonies, Pickr for the visual color picker, and Alpine.js for reactive state management. All data is stored locally in your browser's IndexedDB.

Core Features

  • Color input via text field (HEX, RGB, HSL, or CSS color name) or visual picker.
  • Six harmony types generated automatically: complementary, analogous, triadic, tetradic, split complementary, and monochromatic.
  • Five color formats displayed: HEX, RGB, HSL, CMYK, and LAB.
  • Favorites system with persistent storage, export, and project management.
  • Projects that save your current color and favorites with a timestamp. Projects use the naming convention YYYY-MM-DD--unixtimestamp--project-name.kolora-project.
  • Import/export individual projects or your entire collection.
  • Random color generator for inspiration.
  • Theme switcher (light, dark, system) and multilingual UI.

Privacy

Your colors and projects never leave your device. Kolora runs entirely in the browser with no backend, no accounts, and no tracking.

Use Cases

  • Graphic designers can quickly generate harmonious palettes for branding projects.
  • Web developers can test color schemes and copy CSS‑ready values.
  • UI/UX designers can explore accessibility‑friendly combinations.
  • Artists and illustrators can save inspiration palettes for later use.
  • Educators can teach color theory interactively.

Discover Perfect Color Harmonies

Why Kolora Is the Ultimate Color Palette Generator

Color is the foundation of every design project. Whether you are building a brand identity, designing a website, or creating digital art, the right color palette can make or break your work. Kolora gives you professional‑grade color tools without the complexity of heavyweight desktop software, all within the privacy of your browser.

How Kolora Elevates Your Workflow

Traditional color tools often require accounts, cloud storage, or expensive subscriptions. Kolora takes a different path. It runs entirely on your device using IndexedDB, meaning your palettes, favorites, and projects stay with you forever — accessible even offline.

The application supports five color formats (HEX, RGB, HSL, CMYK, LAB) and generates six harmony types automatically from any base color. Need a complementary scheme for a call‑to‑action button? Enter your brand hex and copy the result instantly. Exploring a triadic palette for an illustration? The swatches update in real time as you adjust.

Project Management for Designers

Unlike simple color pickers, Kolora includes a full project management system. Save your current palette and favorites as a project, name it, and return to it later. Projects use a structured naming convention (YYYY-MM-DD--timestamp--name.kolora-project) making them easy to organize and archive. Export individual projects to share with colleagues or import entire collections to restore your workspace.
