The background component sets a basic color background of a scene that is more performant than a-sky since geometry is not created. There are no undesired frustum culling issues when a-sky is further than the far plane of the camera. There are no unexpected occlusions either with far objects that might be behind of the sphere geometry of a-sky.


The example below sets the background color to red.

<a-scene background="color: red"></a-scene>
