Slack's unusual choice of aubergine (dark purple) as a primary color sets it apart from the sea of blue enterprise tools. The four accent colors (blue, green, yellow, red) from the hashtag logo add warmth and personality.

The warm-cool interplay between aubergine and the bright accents creates energy
Aubergine communicates sophistication and creativity, positioning Slack as more than basic enterprise software. The four bright colors suggest communication, connection, and the mixing of ideas — perfect for a messaging platform.
Slack simplified from a rainbow/plaid logo to the current four-color mark in 2019. The aubergine has been refined from a brighter purple to the current deeper, more professional shade. The marketing has become cleaner while maintaining the playful spirit.
Aubergine (#4A154B) defines the sidebar, dark sections, and primary brand presence — it's the most recognizable element of Slack's interface.
Slack Blue (#36C5F0) highlights active states, links, and notification badges.
Slack Green (#2EB67D) signals online status, success confirmations, and positive actions.
White backgrounds with light gray surfaces keep the workspace clean and content-focused.
Near-black text (#1D1C1D) with warm gray secondaries maintain readability across themes.
The four logo colors naturally map to semantic roles: blue for info, green for success, yellow for warnings, and red (pink) for errors and important notifications.

Aubergine was chosen to differentiate Slack from the typical blue-dominated enterprise software landscape. The deep purple conveys creativity and warmth while maintaining professionalism, helping Slack stand out as a more human-centered work tool.
