Download the Zellbox logo in various formats and sizes for use in documentation, social media, and integrations.

Logo

The mark is a Z glyph inside a violet rounded square, paired with a wordmark in the same family. It signals "platform" and "calm operator workspace" rather than consumer flash — fitting for a CRM operators stare at for hours.

Full logo — dark background

Use over dark backgrounds (e.g. landing hero, slide decks with dark themes).

Brand Colors

The primary palette used across the Zellbox brand. Slate-indigo violet is the primary; the dark navy is the chrome accent (sidebar, dark hero); the semantic colours (emerald, amber, red) are reserved for app state — never used as brand accents to avoid colliding with success / warning / error signals inside the product.

Typography

Zellbox uses Inter (variable) for all UI and brand surfaces. Inter is free, open-source, and ships natively in every modern OS rendering pipeline. Weights: 400 (body), 500 (interactive), 700 (display).

Fall-back stack: Inter, -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, sans-serif.

Usage

• Do preserve clearspace around the logo equal to half the height of the Z tile.
• Do use the violet #4C53A5 tile on its own when space is constrained.
• Don't recolour the Z glyph or change its tile background to a colour outside the palette.
• Don't rotate, skew, or apply drop shadows to the mark.
• Don't place the dark-text wordmark on a violet background — contrast is insufficient. Use the white-text variant instead.
