Get custom colors for the authenticated user
AI agents call getCustomColors to retrieve information from Tweek MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The action is read-only with no blast radius if misused—it merely returns color preference information already accessible to the authenticated user.
