Charcoal Outline

A clean, dark Fluxer theme with a solid charcoal background, transparent main panels, blue feature accents, and thin gray hover outlines.

Features

Solid charcoal background (#1e1e1e).
Transparent main panels with subtle gray borders.
Thin gray hover outlines on targeted controls and selectable rows.
Blue accents for primary actions and selected states.
Distinct danger, warning, success, and presence colors.
Opaque menus, tooltips, and popouts for readability.
System fonts with no external assets or network dependencies.
No custom JavaScript, gradients, glow, or animations.

Installation

Download Charcoal Outline.css from this repository.
Open Fluxer's theme settings and add the stylesheet using the CSS import or editor option available in your client.
Enable Charcoal Outline.

This is a complete replacement stylesheet, not an append-only patch. If you used an earlier version, replace its CSS rather than appending this version.

The exact theme-management controls may vary by client version.

Customization

The palette is defined in the :root, body block near the top of the stylesheet:

--co-background: #1e1e1e;
--co-text: #e8ebf2;
--co-muted: #98a1b3;
--co-accent: #4fa3ff;
--co-danger: #ef6565;
--co-success: #7bdca2;
--co-warning: #f2ce75;
--co-line: rgba(128,128,128,.35);
--co-code: rgba(128,128,128,.2);
--co-hover: rgba(128,128,128,.08);
--co-selected: rgba(79,163,255,.14);

--co-line controls panel borders and gray hover outlines.
--co-accent controls mapped blue feature accents.
--co-hover controls subtle hover fills.
--co-selected controls mapped selection fills.

Some secondary shades and mention backgrounds use explicit color values. Changing --co-accent alone does not recolor every blue detail.

Layout and accessibility

The theme avoids custom sidebar offsets, forced control sizes, clipping workarounds, and resize-handle changes. Native layout and scrolling behavior are left in place as far as practical.

Keyboard-focus indicators remain separate from mouse-hover outlines. Existing selected-server outlines and semantic feature colors are preserved. No custom motion effects are added.

Optional motion addon

charcoal-outline-motion.css is stand alone css that adds subtle animations to Charcoal Outline without changing its colors or layout.

Included effects

Thin gray hover outlines fade in and out.
Buttons compress slightly when pressed.
Server icons lift slightly on hover.
Menus, tooltips, notifications, and message-action toolbars have quick entrance animations.
The composer border transitions smoothly when focused.
Channel and settings rows transition between their existing background colors.
