On June 27, 2015, Noah Slater sent an email to the Unicode Consortium-the organization that approves new emoji-and requested that they officially add an emoji that depicted a rainbow flag. The Microsoft version of the emoji depicts the flag attached to a grey flag pole. On Twitter, the flag resembles a rectangle with rounded corners. On most major platforms, the emoji depicts a flag waving in the wind that has, starting from the top, a red, orange, yellow, green, blue, and violet stripe. The emoji is a combination of the White Flag emoji 🏳️ and the Rainbow emoji 🌈.
The Rainbow Flag emoji 🏳️🌈, also popularly called Pride Flag emoji, was added to Emoji 4.0 in 2016.
