Intelligent Color Selection Assistant

The intelligent color selection assistant can intelligently and randomly recommend a color based on the user's input exclusion color list. By integrating an AI agent and custom JavaScript code, this workflow automatically handles color filtering and selection, supporting both manual and chat message triggers. It provides flexible color inspiration for designers, product managers, and others, enhancing selection efficiency and suitable for various scenarios that require dynamic color generation, showcasing the powerful application capabilities of the combination of AI and code.

Workflow Name

Intelligent Color Selection Assistant

Key Features and Highlights

This workflow, built on the n8n automation platform, integrates LangChain’s AI Agent with the OpenAI GPT-4o-mini model to intelligently return a random color choice based on a user-provided exclusion list. It employs a custom JavaScript code tool to filter out specified colors and perform random selection. The workflow supports both real-time triggers and chat message triggers, offering flexible and responsive user interaction.

Core Problem Addressed

When users need to randomly select a color, they often want to exclude certain colors (e.g., avoiding green and blue). Manual filtering is cumbersome and prone to errors. This workflow combines AI with code tools to automatically handle exclusion logic, quickly and accurately providing suitable color recommendations, thereby improving efficiency and precision.

Application Scenarios

  • Designers or product managers seeking quick color inspiration while excluding unsuitable colors
  • Automated systems requiring dynamic generation of color choices that meet specific criteria
  • Educational or demonstration settings showcasing the integration of AI customization logic with code
  • Any automated process needing random selection of items based on exclusion conditions

Main Workflow Steps

  1. Triggered either manually by clicking “Test Workflow” or via incoming chat messages.
  2. Receives the user’s exclusion color list through a “Debug Input” node or chat input.
  3. The AI Agent invokes a built-in “Code Tool” to execute JavaScript logic that filters out the specified colors from a predefined color set.
  4. Randomly selects one color from the remaining options and returns the result.
  5. The AI Agent leverages the OpenAI GPT-4o-mini model for language understanding and response optimization, ensuring intelligent and natural interaction.
