+### Keyhole color

+Use the keyhole color to support contrast without changing the official icon:
+
+- **Primary app icon / launcher / store icon:** keep the approved dark keyhole. It feels private and
+  premium, and keeps the icon from looking like a generic security app.
+- **Transparent mark on dark aubergine or purple:** use the white-keyhole variant so the privacy
+  cue stays visible.
+- **Transparent mark on blush, white, or light UI:** use the aubergine-keyhole variant first; use
+  the black-keyhole variant only when maximum contrast is needed.
+- **Notification small icon:** use the single-color platform glyph; do not use the full-color
+  launcher art.
+- **Loading mark:** use the aubergine-keyhole variant on light/card surfaces.
