**Short description of error**
It appears that the Movie Clip Editor grid color cannot be adjusted. Changing the grid color setting does not have an effect.
Also the Video Sequence Editor and the Node Editor actually lack the option to change the grid color entirely, and while that may be by deliberate design I thought I should bring it up since other editors which have grids do offer that option.
**Exact steps for others to reproduce the error**
1. Set part of your workspace to the Movie Clip Editor. Note the grid color.
2. Open Blender's Preferences and go to the Themes tab.
3. Navigate to the Movie Clip Editor section and under the Theme clip Editor heading find the color for "Grid".
4. Change that color value and observe how the grid color in the Movie Clip Editor does not change.
