Reversed logo 
Slack
Workplace messaging platform that revolutionized team communication with its colorful, approachable brand identity.
Slack’s logo represents one of the most thoughtful rebrands in modern tech history. The 2019 redesign by Pentagram’s Michael Bierut transformed the company’s original hashtag-inspired octothorpe into a simplified, more versatile mark that maintains Slack’s signature playfulness while solving critical usability problems.
Logo History
Slack’s original 2013 logo featured eleven different colors arranged in a plaid-like pattern of four rotated overlapping shapes. While visually distinctive, it proved notoriously difficult to reproduce accurately across different contexts. The 2019 rebrand reduced the palette to just four vibrant colors—aubergine, blue, green, yellow, and red—arranged in a cleaner, more modern configuration. This evolution maintained the brand’s approachable personality while dramatically improving consistency across digital and physical applications.
Design Philosophy
The current Slack logo achieves remarkable balance between friendliness and professionalism. The rounded, symmetrical shapes suggest connection and accessibility, while the carefully calibrated color palette feels energetic without overwhelming. Pentagram designed the mark to work seamlessly at any size, from favicon to billboard, addressing the original logo’s reproduction challenges while preserving Slack’s core identity as a tool that makes work more human.
Brand Identity
Slack’s visual language extends far beyond the logo into a comprehensive design system that emphasizes clarity, warmth, and personality. The brand’s signature colors appear throughout the product interface, marketing materials, and custom emoji library. This consistency reinforces Slack’s promise to bring order and enjoyment to workplace communication, transforming the often-sterile category of enterprise software into something genuinely delightful.
Cultural Impact
Slack’s rebrand demonstrated that enterprise software doesn’t need to look corporate or cold. The logo’s friendly geometry and vibrant palette influenced countless SaaS brands to embrace more approachable, human-centered design. By proving that workplace tools could be both powerful and playful, Slack helped shift the entire technology industry toward more colorful, personality-driven brand identities that prioritize user experience and emotional connection.
Clear Space
Maintain adequate clear space around the Slack logo to ensure visual integrity and maximum legibility. The minimum exclusion zone equals the height of the logo's cap height (represented as "x") on all sides. This protective space prevents the logo from appearing cluttered when placed near other graphic elements, text, or page edges.
