# Slack — Design System

## Overview

Slack's design system embodies the Sage and Creator archetypes, delivering a sophisticated yet accessible user experience. It aligns with the aesthetic principles of comparable brands like Asana, Notion, Linear, and Figma, emphasizing clarity, efficiency, and modern professionalism. The visual language is meticulously structured, reflecting an enterprise-ready platform designed for optimal productivity and seamless collaboration. This design ethos prioritizes functional elegance, ensuring that every interface element contributes to a focused and intuitive workflow.

This system intentionally steers clear of overly playful or minimalist-for-minimalism's-sake aesthetics. It avoids the starkness of purely utilitarian interfaces while also eschewing the decorative flourishes found in consumer-first applications. The design is not a blank canvas; it is a thoughtfully organized workspace. It does not aim for disruptive novelty but rather for consistent, reliable performance, visually reinforcing Slack's position as an indispensable tool for structured, modern work environments.

## Do's and Don'ts

### Do

- Use Salesforce-Sans (400 weight) for all body copy and Salesforce-Avant-Garde (600 weight) for primary headings.
- Format all headings in sentence-case; do not use title case or all-caps for main headers.
- Apply the primary brand color #611f69 to primary CTA buttons with white (#ffffff) text.
- Style primary buttons with 4px border-radius, 12px vertical padding, and 16px horizontal padding.
- Use subtle depth effects: apply a 1px inset shadow (rgb(97, 31, 105) 0px 0px 0px 1px inset) to secondary buttons and a soft drop shadow (rgba(0, 0, 0, 0.1) 0px 5px 20px 0px) to elevated elements.
- Utilize a clean white (#ffffff) background for light mode interfaces to maximize readability.
- Incorporate subtle radial gradients (e.g., rgba(255, 100, 150, 0.25)) sparingly in hero sections to add visual interest without clutter.
- Keep button border-radius consistent at 4px for primary actions and 0px for outline/tertiary navigation buttons.

### Don't

- Do not use emojis in marketing copy or UI labels; maintain a text-only professional tone.
- Avoid exclamation points in headlines and body copy; keep the tone matter-of-fact.
- Do not use serif fonts; the brand is strictly sans-serif (Salesforce-Sans/Avant-Garde).
- Avoid title-case formatting for headings; this breaks the established sentence-case convention.
- Do not use bright, saturated colors outside the #611f69/#4a154b purple spectrum for primary branding elements.
- Avoid pill-shaped (fully rounded) buttons for primary actions; stick to the 4px radius.
- Do not use heavy, hard shadows; keep all shadows soft and diffuse (e.g., 20px blur radius).
- Avoid dense jargon in primary messaging; keep vocabulary moderate and accessible to non-technical stakeholders.
