WHY IT NEEDS A POLICY

Why set_track_color needs a policy

This tool creates or modifies data in a reversible manner by changing the visual color attribute of a mixer track. It does not execute code, delete data, move funds, or perform irreversible operations. The change can be easily undone by setting a different color. Therefore, it falls under the Write category with low severity due to minimal impact on audio production workflow.

From the tool's definition Tool name 'set_track_color' and description 'Set the color of a mixer track' indicate modification of track metadata (color property). This is a reversible change to mixer track properties in FL Studio.
