Slack Brand Colour Reference

Slack is a business communication platform offering messaging, file sharing, and integrations.

Colour references

• Aubergine #4A154B
• Blue #36C5F0
• Green #2EB67D
• Yellow #ECB22E
• Red #E01E5A

The aubergine base is unusual for a productivity tool, making Slack feel less corporate and more human. The four accent colours create a playful system that maps to different notification types and channels, turning a functional tool into something with personality.
