How can we help?

Import the package via the Unity Package Manager or the Asset Store tab in the editor. Once imported, go to Window → Two Green Pigs → Hierarchy Colorizer to open the settings window. The tool activates automatically — no scene setup required.

Hierarchy Colorizer supports Unity 2021.3 LTS, 2022.3 LTS, 2023.x, and Unity 6 (6000.x). If you experience issues on a specific version, please contact us.

Rules are matched top-to-bottom — the first matching rule wins. You can match by name (contains, exact, starts with, ends with), by Tag, or by Layer. Drag rules in the settings window to reorder them. Enable Apply Colors to Children to inherit colors down the hierarchy.

Hover over any row in the Hierarchy — a small ✦ button appears on the right. Click it to open the color picker and choose a color. This per-object override has the highest priority and overrides all rules. A colored swatch stays visible on the row; click × to clear it.

Colors defined by rules persist automatically via the Settings asset. If per-object overrides disappeared, make sure the HierarchyColorizerSettings asset is saved in your project (not inside a Temp folder). If the issue persists, please email us with your Unity version.

Open the Hierarchy Colorizer settings window and disable Show Component Icons, or reduce the number of columns displayed. You can also disable individual features (hover toggle, per-object color picker) to free up space on each row.

Yes. Rule-based colors work in prefab mode. Per-object overrides use GlobalObjectId to identify objects, so they work in the scene hierarchy. Inside prefab isolation mode behavior may vary depending on the Unity version.

Click the Reset to Defaults button at the bottom-left of the Hierarchy Colorizer window. This restores all general settings and clears all rules. Per-object overrides are stored separately in the Settings asset — you can clear them by deleting the Color Overrides list directly in the Inspector.
