# KoTalk Brand Guide
|
|
|
|
## Overview
|
|
|
|
This package turns the approved raster logo concept into a reusable production asset set for KoTalk.
|
|
|
|
- Reference intent: warm, calm, modern messenger mark
|
|
- Primary use: app icon, favicon, PWA icon, Windows icon, docs, release pages
|
|
- Master source: `branding/kotalk-logo-master.svg`
|
|
|
|

## Color System
|
|
|
|
### Core colors
|
|
|
|
- Ink: `#394350`
|
|
- Warm accent: `#F05B2B`
|
|
- Separator white: `#FFFFFF`
|
|
|
|
### Supporting backgrounds
|
|
|
|
- Paper: `#F7F3EE`
|
|
- Night: `#141922`
|
|
|
|
### Recommended backgrounds
|
|
|
|
- White: `#FFFFFF`
|
|
- Warm paper: `#F7F3EE`
|
|
- Dark surface: `#141922`
|
|
|
|
## Safe Area
|
|
|
|
- Artboard: `1024 x 1024`
|
|
- Recommended clear area from the artboard edge: `128px`
|
|
- Do not scale the visible mark so large that any speech bubble or the center chevron approaches the outer 12% of the square
|
|
|
|
## Minimum Use Size
|
|
|
|
- Preferred minimum digital size: `24px`
|
|
- Favicon minimum: `16px`
|
|
- When rendering below `24px`, use the packaged ICO or PNG exports instead of re-rasterizing from screenshots
|
|
|
|
## Usage Rules
|
|
|
|
- Keep the mark square, centered, and unrotated
|
|
- Use the transparent master for docs and UI surfaces when the background is already controlled
|
|
- Use the white background exports for launcher and touch icons
|
|
- Use the mono variants only where a single-color system is required
|
|
|
|
## Do Not
|
|
|
|
- Stretch or rotate the mark
|
|
- Add shadows, glow, gradients, glass, or texture
|
|
- Change the orange or dark brand colors arbitrarily
|
|
- Add pattern backgrounds behind the mark
|
|
- Recreate the logo from screenshots when the packaged vectors are available
|
|
|
|
## Regeneration
|
|
|
|
Run:
|
|
|
|
```bash
|
|
python scripts/branding/generate_kotalk_brand_assets.py
|
|
```
|
|
|
|
This regenerates the committed vector, PNG, ICO, and app-facing icon assets from the scripted master geometry.
