background
The background variable is one of three important scene state variables. The background should be a 4-vector (in the order of red, green, blue, alpha; values 0 to 1)that dictates the color of the background of the screen. Like the camera variable, you should not modify it during slide initialization (with exception to the config slide), and instead use animations such as Set or Lerp. By default, the background is fully black, although I personally think Monocurl looks better in a light theme.
The background variable is definitely important, and even though it is simple, you should probably memorize its function.
In the majority of cases, I find it better to have the background be constant throughout the scene, and if we really need a changing background to do so via a rectangle that changes color or something similar. The reasons are somewhat personal, but I feel the background should set the theme of the scene, and it doesn't make all that much sense to change the theme in the middle. Nevertheless, this option exists.
