வானவில்

The colorful arc of a rainbow, as may appear after rain. Generally depicted as the left half of a full rainbow, showing six bands of color: red, orange, yellow, green, blue, and violet.

Commonly used to express gay pride. Also commonly used to convey various feelings of love and happiness. See also 🏳️‍🌈 Rainbow Flag.

WhatsApp’s design shows the right arc of rainbow disappearing into a cloud. Facebook’s rainbow is displayed on a blue sky, as Apple, Samsung, and Twitter’s previously were. Google and Microsoft previously displayed full rainbow arcs with clouds.
