Colors in the user interface can be customized. Here is an example:
Go to the menu Tools -> System Settings -> Color Settings -> 3D colors, background and cursor. Click on the "Set selected group" button. In the right window, the colors for the X, Y and Z axis can be changed.
We recommend changing color palette first. Customize colors, if you are not satisfied with available palettes. If you create your own colors, save them as a new palette.
