Window System Introduction
After starting Blender and closing the Splash Screen the Blender window should look something similar to the image below; as Blender’s user interface is consistent across all platforms.
Blender’s interface is separated into three main parts:
Blender also makes heavy use of keyboard shortcuts to speed up work. These can also be customized in the Keymap Editor.
Blender allows for most of its interface color settings to be changed to suit the needs of the user. If you find that the colors you see on screen do not match those mentioned in the Manual then it could be that your default theme has been altered. Creating a new theme or selecting/altering a pre-existing one can be done by selecting the Preferences editor and clicking on the Themes tab.
