How to reproduce:
1. Create and open a new project
2. Import the “LabelFieldExample.cs“ Script
3. Open the “Example > Editor GUILayout Label Usage“ Window in the Toolbar
4. Observe the Custom Editor Window

Expected result: The text is white and bolded
Actual result: The text is black, but bolded

Reproducible in: 2021.3.44f1, 2022.3.50f1, 6000.0.23f1

Reproduced on: Windows 11 Pro (23H2)
Not reproduced on: No other environment tested

Notes:
- It seems, the style is deliberately making the text white, because by default the unstyled color is gray
- the “EditorStyles.whiteLabel” parameter colors the text white
