How to reproduce:
1. Create a new Unity project
2. Open the Animation window and create any Animation Clip for any GameObject
3. Add any Property
4. Deselect the Property and observe the contrast of the Property name text and the background

Expected results: The name text uses the standard text color used across the Editor and the contrast is normal
Actual results: The contrast of the text color and the background is poor

Reproducible with: 2022.3.61f1, 6000.0.51f1, 6000.1.0b8, 6000.2.0b4

Reproducible on: macOS Sequoia 15.4 (M1)
