04Usage notes
Derived from the public websiteSuiteAnvil derived these notes from the logo, colors and contrast measured on slack.com on 11 Nov 2026. They are practical defaults, not Slack's official brand guidelines. Where Slack publishes its own rules, those win.
Clear space
Keep free space of at least half the logo height on every side (dashed line). Nothing else, including text and edges of photos, enters that zone.
Minimum size
- Screen
- 16 px
- 5 mm
Logo height, for the wide logo or wordmark. Below that, use the square icon or set the name in Salesforce Avant Garde instead.

Do not recolor
- Use the logo in #1D1C1D, in solid black or in solid white only. Do not swap in other palette colors, gradients or tints.
- Avoid placing the #1D1C1D logo on #730394 and #4A154B: contrast stays below 3:1. Use the white or black version there.
- Do not stretch, rotate, outline, crop or add shadows and effects.
- Do not rebuild the logo from a font; download the file above.
