Returns a LAB (CIELAB) color.
AI agents call color-lab to retrieve information from Faker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool generates fake/random color data using Faker.js. It only returns data and has no side effects, making it a Read category tool with low severity.
