2.81a, 2.82 Beta.
In 3D View, the grid color overlays the XYZ axis colors, so it's impossible to set the colors I want to the XYZ axis.
This even happens if the grid color is set to transparent.
Exact steps for others to reproduce the error
- Go to preferences -> Themes -> User Interface -> Axis & Gizmo Colors
- Change X and Y axis color to black RGB(0, 0, 0)
- Go to preferences -> Themes -> 3d View
- change Grid color/alpha.
X and Y axis color will be affected
