Tallinn Theme for Slack

The Codigrate Tallinn theme for Slack. Preview the screenshot and the palette, then get it in a few steps.

Inspired by Tallinn's crisp light and Baltic calm, this theme pairs airy porcelain backgrounds with cool Nordic blues for a clean, focused coding experience. Soft, bright surfaces enhance readability, while deep ink accents and subtle lavender-rose highlights add clarity and warmth without losing its minimal Northern character.
