<a-sky>

The sky primitive adds a background color or 360° image to a scene. A sky is a large sphere with a color or texture mapped to the inside.

Example

An equirectangular image as a background:

<a-scene>
  <a-assets>
    <img id="sky" src="sky.png">
  </a-assets>
  <a-sky src="#sky"></a-sky>
</a-scene>

A plain color as a background:

<a-sky color="#6EBAA7"></a-sky>

To be seamless, images should be equirectangular. We can find some sample equirectangular images on Flickr. To take an equirectangular photo, check out this 360-degree photography guide.
