Slack Logo
The Slack logo pairs a four-colour pinwheel mark in aubergine #E01E5A, blue #36C5F0, green #2EB67D and yellow #ECB22E with a wordmark set in a custom rounded geometric sans-serif. The current symbol, a stylised hashtag built from overlapping speech-bubble shapes, was designed by Pentagram in 2019 to replace the busier original.

Slack Logo History & Meaning
Slack launched publicly in 2014 and adopted its now-famous hashtag-style mark, an octothorpe built from overlapping speech-bubble lobes. In 2019, ahead of its direct stock listing, the company replaced that busy eleven-colour emblem with a cleaner four-colour pinwheel designed with the studio Pentagram, reducing the palette to aubergine, blue, green and yellow. The refreshed symbol keeps the lozenge shapes but arranges them around a central point so the logo reads consistently on dark and light backgrounds. The wordmark sits beside the icon in a rounded, friendly sans-serif that matches the mark's approachable tone.

Slack Logo FAQ
What font is used in the Slack logo?
The Slack wordmark uses a custom geometric sans-serif drawn for the brand, with rounded terminals that feel similar to typefaces like Circular or Lato. It is a bespoke lockup rather than a stock font you can install.
What are the Slack brand colours?
The 2019 pinwheel mark uses four colours: aubergine pink #E01E5A, blue #36C5F0, green #2EB67D and yellow #ECB22E. The wordmark itself is usually shown in a near-black aubergine on light backgrounds.
Who designed the Slack logo?
The current four-colour logo was created in 2019 by the design studio Pentagram, replacing the original 2014 hashtag emblem. The redesign coincided with Slack's move toward its public stock listing.
What does the Slack logo mean?
The mark is a stylised octothorpe (hash symbol), a nod to the channel naming convention used throughout the app. Its overlapping lozenge shapes evoke speech bubbles and the idea of conversations coming together in one place.
Where can I get the official Slack logo?
Slack publishes its logo files and usage rules in its official Media Kit at slack.com/media-kit, which links to a managed asset library for the marks. Always download from that source and follow Slack's trademark guidelines.
