Steps to reproduce:
# Create a 3D project
# Add 3D Object -> Cube
# Update "Editor Theme" to "Light" one (on Mac: Unity ->Preferences ->General)
# Window -> Search -> New Window
# Enter the search string "Cube"
# Save search results to the "Project" list (diskette -> Save Project)
# A newly saved query should become visible in the "Project" list
# Select it and observe it

Expected result: The background should become blue, query title and results amount should be visible and readable. 

Actual result: The background becomes blue, and the query title becomes white and visible, but the results amount doesn't change its color. It is grey and poorly visible. Added screenshot in the "Attachments" section.

Reproducible with: 2021.3.22f1, 2022.2.14f1, 2023.1.0b11, 2023.2.0a9.

Cannot test with: 2020.3.46f1 (this stream has no this window).
