A pretty rainbow emoji in a clear sky, which tends to appear when there is a light rain or mist in the air, at the same time as sunshine.
The Google version of this artwork features a cloud at both ends of the rainbow, whereas the Apple artwork only shows a section of the rainbow.
This emoji can be used in the context of weather, or alternatively in support of gay pride.
Rainbow was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
