Slacque

Custom Slack themes, generated from any logo, inside Claude Code.

Drop in a logo, get back the 4-hex string Slack expects in Preferences → Themes → Customize Your Theme → Import. Slacque reads the dominant brand colors with vision, optionally cross-checks the brand's website for official hex codes, and assembles a palette that fits Slack's 4-slot model. Refine it conversationally until it feels right.

Example

#0E8074, #1E2D8C, #20A271, #3B4FE0

(Generated from a logo with a teal wordmark and navy accent.)

Install

/plugin marketplace add rashad/slacque
/plugin install slacque@slacque

Then reload (/reload-plugins) and run /slacque:slacque.

Tip: just type /sla — Claude Code's slash menu surfaces the command on the first match.

git clone [email protected]:rashad/slacque.git
/plugin marketplace add /path/to/slacque
/plugin install slacque@slacque

Usage

/slacque:slacque ~/Downloads/acme-logo.png

You can also drag-and-drop the logo into the terminal after typing /slacque:slacque (with a trailing space), or paste an image (Cmd+V) after /slacque:slacque with no argument.

For recognizable brands, Slacque will offer to check the brand's website for official colors before producing the palette (requires WebSearch and WebFetch permissions in Claude Code).

Refining

After the first output, iterate in plain English:

• "darker" / "lighter"
• "less saturated" / "more saturated"
• "change the accent" / "warmer badge" / "cooler badge"
• "another angle" / "try again"
• "light theme" / "dark theme"
• "keep everything but the mention"

Each refinement re-emits the full palette — no partial diffs.

How the 4 slots work

Slack accepts 4 hex codes and derives the rest of the UI from them:
