Slack's identity is built around the idea that work should feel human and even a little fun. The canonical surface is **light** — white content areas with a deep aubergine (`#4A154B`) sidebar — the inverse of dark-first tools. This contrast is intentional: the sidebar is a calm, always-present navigation anchor, while the content area is bright and open.
