Aether Core uses a controlled accent system rather than covering the interface with bright colors.
| Variant | Character |
|---|---|
| Aether Blue | Primary atmospheric accent |
| Deep Violet | Secondary depth |
| Mineral Cyan | Cool highlight |
| Emerald | Natural secondary accent |
| Solar Gold | Warm emphasis |
| Moon Silver | Neutral highlight |
| Core White | Light-mode clarity |
90% calm material, 10% accent energy.
Accent colors are reserved for:
- Important states
- Active elements
- Navigation
- Interaction
- Selected content
- Visual emphasis
The interface remains calm while the accent system provides controlled energy.
Aether Core is built around layered surfaces.
| Layer | Purpose |
|---|---|
| Core Surface | Main workspace |
| Primary Surface | Editor and writing areas |
| Raised Surface | Panels and tables |
| Glass Layer | Special interface elements |
| Accent Layer | Active and important states |
The material system follows one rule:
Everything should feel like it belongs to the same environment.
Nothing should appear pasted onto the interface.
Tables use the same material language as the rest of Aether Core.
| Element | Design |
|---|---|
| Header | Elevated surface |
| Body | Single continuous surface |
| Rows | No alternating colors |
| Borders | Soft mineral edges |
| Hover | Subtle accent reflection |
Aether Core deliberately avoids zebra-striped tables.
The intended feeling is:
A table carved into the same surface as the note.
| Purpose | Font |
|---|---|
| Body | Inter |
| Headings | Cormorant Garamond |
| Code | JetBrains Mono |
Typography is designed to remain elegant without sacrificing readability.
The content always remains more important than decoration.

Aether Core is built around a simple idea:
The interface should support knowledge, not compete with it.
The theme uses atmosphere carefully.
Material provides the structure.
Typography provides clarity.
Accent colors provide energy.
Effects provide depth.
The content remains at the center.
Aether Core follows a controlled visual balance:
| Element | Role |
|---|---|
| Material | Foundation |
| Typography | Information |
| Accent | Energy |
| Glass | Depth |
| Glow | Emphasis |
| Decoration | Minimal |
The design avoids turning every element into a visual feature.
When everything glows, nothing feels important.
