## Description The terrain colors settings refactor (#4391) inadvertently changed the **default** land terrain colors. The PR moved the hardcoded terrain colors into configurable settings, but the new default hex values in `render-settings.json` — combined with the new shading math — no longer reproduced the original sand/plains/highland appearance. In particular the new shading formulas use each JSON color as a *base* and apply offsets differently (e.g. highland now adds `2*(magnitude-10)` instead of `2*magnitude`), so the default hex values needed to compensate. ## Fix Surgical, JSON-only change to the defaults so the new formulas produce **pixel-identical** output to the pre-#4391 code: | Terrain | Was (#4391) | Restored | | --- | --- | --- | | sand | `#CC9E9E` | `#CCCB9E` | | plains | `#BECD8A` | `#BEDC8A` | | highland | `#C8B78A` | `#DCCB9E` | | mountain | `#e6e6e6` | `#e6e6e6` (unchanged) | | ocean | `#4785b5` | `#4785b5` (unchanged) | The settings/UI machinery from #4391 stays intact and users can still override colors — only the defaults are corrected. Verified across all magnitude/shoreline combinations that the rendered land colors match the original output exactly. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>

🚀 Installation
-
Clone the repository
git clone https://github.com/openfrontio/OpenFrontIO.git cd OpenFrontIO -
Install dependencies
npm run instDo NOT use

🎮 Running the Game
Development Mode
Run both the client and server in development mode with live reloading:
npm run dev
This will:
- Start the webpack dev server for the client
- Launch the game server with development settings
- Open the game in your default browser (to disable this behavior, set
SKIP_BROWSER_OPEN=truein your environment)
Client Only
To run just the client with hot reloading:
npm run start:client
Server Only
To run just the server with development settings:
npm run start:server-dev
Connecting to staging or production backends
Sometimes it's useful to connect to production servers when replaying a game, testing user profiles, purchases, or login flow.
To replay a production game, make sure you're on the same commit that the game you want to replay was executed on, you can find the
gitCommitvalue viahttps://api.openfront.io/game/[gameId]. Unfinished games cannot be replayed on localhost.
To connect to staging api servers:
npm run dev:staging
To connect to production api servers:
npm run dev:prod
