What is the name of Google’s open-source font family that includes colored emoji designs?

Google’s open-source font family containing colored emoji designs is Noto Color Emoji.

Noto is Google’s broad font project, created to support writing systems across the world and reduce the problem of missing-glyph boxes. Noto Color Emoji extends that goal to pictographic characters, including many emoji encoded in Unicode.

The font is used in parts of Google’s software ecosystem, including Android and ChromeOS. Its designs are maintained alongside the wider Noto project, although the exact appearance of an emoji can still differ when another operating system or application supplies its own font.

Noto Color Emoji is not the same thing as a Unicode release. Unicode defines character identities and sequences, while a font supplies the visual artwork used to display them. This distinction explains why one emoji can look different on Google, Apple, Microsoft, or Samsung devices.
