Outlook

Outlook's product palette, anchored on the Outlook envelope-with-O mark (a deep-navy envelope, a pale-blue flap, and the white "O" ring) and on Microsoft's Communications Blue (#0067B8 / #0078D4) as the primary product action color. Outlook is a product-brand under the Microsoft parent (see brands/microsoft/1.0.0); it inherits Microsoft's Fluent design language, the Segoe UI typographic family, and the enterprise-clear voice.

Swatches

outlook-deep-blue
#2A446F
The outer-envelope navy. Captured from the SVG fill on the Outlook logo on outlook.live.com. The dominant identity hue of the Outlook mark.
outlook-action-blue
#0066FF
The "O" ring on the Outlook envelope and the brand's vibrant mid-blue. Used on the live product surface for the logo letter-mark fill.

#B3DAF0
The pale-blue envelope flap on the Outlook mark. A light-tint accent that softens the deep-navy outer fill.
communications-blue
#0078D4
Microsoft's Fluent system primary, inherited from the Microsoft parent. The canonical CTA / link affordance across Outlook product chrome.
outlook-link-blue
#0067B8
The action-text blue captured from outlook.live.com — Fluent's darker brand variant used for links and primary buttons on light surfaces, where #0078D4 would lose AA contrast on small type.

Notes
Outlook color values captured from the live outlook.live.com product on 2026-05-18 — the envelope-mark SVG fills (deep navy #2A446F, sky #B3DAF0, action blue #0066FF) and product chrome (text #17253D, action text #0067B8, page background #FFFDFB). This is brand-atoms' read of public Outlook surfaces; not an official Microsoft brand document. Outlook inherits its typography (Segoe UI) and Communications Blue primary from the Microsoft parent atom; the values here are the Outlook-specific envelope mark hues plus the Microsoft baseline neutrals.
