setting accent color in workspace settings

Basically the title, I got an error when attempting to do that saying that that setting was only available in user settings. It would help me distinguish between workplaces quicker when alt-tabbing if you could set it in the workspace as well.

Start by reviewing how the VS Code theme handles user settings and why the accent-color setting is rejected in workspace settings. Compare the available user and workspace configuration scopes, then verify that a workspace-specific accent color changes that workspace's appearance while preserving the existing user setting behavior.
