Turns the whole screen a solid color, excepting foreground-layer animations like hit sparks and "ontop" explods. Foreground layers of the stage will not be visible.

Required parameters:

- none

Optional parameters:

- value = col_r,col_g, col_b (int)
  Specifies the R, G, and B components of the color to set the screen to. Each component should be an integer between 0 and 255. The larger a component, the more of that color will appear in the environment color. The default is 255,255,255 (pure white).
- time = effective_time (int)
  Specifies how many ticks the environment color should be displayed. Defaults to 1 tick. Set to -1 to have the EnvColor persist indefinitely.
- under = under_flag (boolean)
  Set under_flag to 1 to have the environment color drawn under characters and projectiles. In other words, characters and projectiles will be visible on top of the colored backdrop.
  Defaults to 0.
