  Interface for Color Harmony Genius

Inspiration Color is one of the most powerful elements in design, whether you're working on a graphic project, redecorating a room, or putting together an outfit. As someone who loves aesthetics and symmetry, I wanted to create a tool that made it easy — and even fun — to find harmonious color combinations based on real color theory.

What it does Color Harmony Genius helps users instantly generate complementary color palettes. Here's what it offers:

Choose any color with a simple color picker

Instantly receive three complementary color suggestions based on established color theory rules

Export your palette as a BMP image file for offline reference — great for shopping, painting, or planning

It’s the perfect companion for designers, decorators, or anyone making visual decisions.

How we built it Built using Bolt.new, the development process was fast and efficient. Bolt.new’s AI tools made it easy to:

Create an intuitive color picker

Apply color theory calculations

Build a palette export feature that generates BMP files We used JavaScript and HTML/CSS as the base, with help from Bolt.new to streamline and enhance development.

Challenges we ran into Converting dynamic color data into a downloadable BMP format was a technical hurdle

Ensuring accurate complementary color calculation across different color spaces (like RGB vs. HSL)

Keeping the UI clean while offering enough features for power users

Accomplishments that we're proud of A simple, clean tool that delivers real, useful results for creatives

BMP export function works flawlessly for offline use

Visual output matches professional-grade color matching tools — all built in a lightweight, user-friendly package

What we learned How to programmatically work with color spaces and generate harmonious palettes

Techniques for creating image files (BMP) directly in-browser using JavaScript

How small utilities like this can have big impact when built thoughtfully

What's next for Color Harmony Genius Add support for different harmony types: analogous, triadic, split-complementary, etc.

Export to more file types like PNG, PDF, or even SVG for designers

Include hex/RGB/CMYK values alongside visual palettes

Mobile-first redesign to make it easier to use on the go

Save and share color palettes via URL or user accounts
