Building an API: Generating Names for Hex Colors

I recently created an API that generates names for hex colors.

Project Concept

The idea behind this project was to create a simple but powerful API that takes a hex color code as input and returns a name associated with that color. This adds a layer of human-readable context to hexadecimal color representation.

Technical Implementation

Step 1: Planning and Design

I started by outlining the API’s functionality and defining the endpoints. The API would accept a hex color code through a GET/POST request and respond with a JSON object containing the color code and its corresponding name.

Step 2: Data Source

I researched existing datasets and libraries, eventually to use a curated list that balanced comprehensiveness and accuracy.

Step 3: Algorithm Design

I developed an algorithm that matches the provided hex color code with the closest color name from the dataset. This involved calculating color similarity based on RGB values and selecting the closest match using a distance metric.

Step 4: API Development

I built it with Express.js, I implemented the API endpoints, ensuring proper validation and error handling. I tested each endpoint locally.

Step 5: Testing

I tested it with different platforms like Postman and insomnia using different hex color inputs to validate accuracy and performance. This included edge cases such as invalid hex codes and boundary conditions.

Use Cases and Applications

The API I developed can be used in a lot of applications, from graphic design tools that suggest color names to educational platforms

Conclusion

Building this API was easy. It taught me valuable lessons in API design, data handling, and so on.

Why HNG Internship?

I plan on gaining knowledge and experience from colleagues and coordinators, refining my skills, and mastering powerful backend features and best practices in the HNG Internship. I’m also very excited to work on real-world projects, collaborate and work with other developers, and deepen my understanding of Backend development.
