The sky primitive adds a background to a scene or display a 360-degree photo. It is an entity that prescribes a large sphere with the material 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>

Equirectangular Image

In order 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.
