In 2D sections, the back wall of a gravity field has arrows pointing along the direction of gravity, and is color-coded: blue for down, red for up, green for right, and gray or purple for left. Some Arrow Switches are connected to them; they can also change direction with the music, like Beat Blocks. Gravity fields are the main mechanic of Bowser's Dark Matter Plant in Super Mario Galaxy, and Rightside Down Galaxy and Upside Dizzy Galaxy in Super Mario Galaxy 2. They usually point in cardinal directions, with an exception in Battle Belt Galaxy.
A type of gravity field navigated in 3D appears in Toy Time Galaxy. It is a hexagon-textured, usually pink surface that pulls gravity toward it. These gravity fields are green on Mecha-Bowser. Occasionally, nearby arrows help indicate the gravity direction of a field.
In Super Mario Galaxy 2, the background of Flipsville Galaxy has similar arrows to a 2D gravity field. However, Mario or Luigi changes their direction by flipping between sides of a planetoid, by Ground Pounding grates or drilling through dirt patches. Unlike true gravity fields, they do not affect all of the objects they encompass, only indicating the player character's gravity.
Gravity fields return in Super Mario Odyssey, where they appear in some of the 2D sections accessed by 8-Bit Pipes. Inside the Inverted Pyramid, the arrows on the gravity fields are designed after the pyramid itself.
