-# ColorCalc – Interactive Colour Range Analyzer
+# ICRS (Interactive Color Range Analyzer)
 
-ColorCalc is a desktop app for Windows/macOS/Linux that helps you identify and highlight colours in images. It is built with Python, Tkinter, and Pillow and is tuned for full‑HD screens. Instead of focusing on a single hue (like purple), you can target any colour range, tweak saturation/value thresholds, and export overlays in seconds.
-
----
+ICRS is a small Tkinter tool for analysing colour ranges in images. You load a picture, pick or click a reference colour, adjust hue/saturation/value sliders, and the app marks matching pixels while showing quick stats.
 
 ## Features
+- Two synced previews (original + overlay)
+- Hue/Sat/Value sliders with presets and image colour picker
+- Exclusion rectangles to ignore regions
+- Theme toggle (light/dark) with rounded toolbar buttons
+- Folder support with previous/next navigation
+- Quick overlay export (PNG) and optional defaults via `config.toml`
 
-- 🎯 **Configurable hue detection** – adjust hue, saturation, and value windows or pick colours directly from the image/preset swatches.
-- 🪟 **Responsive dual-preview UI** – original image on the left, processed overlay on the right, sized for 1080p.
-- 🖱️ **Interactive masks** – draw exclusion rectangles to ignore specific regions when calculating results.
-- 🌗 **Light & dark mode** – rounded toolbar buttons adapt to the current theme; toggle any time.
-- 🟨 **Real‑time stats** – centre-aligned labels show match ratios with/without exclusions plus filenames and dimensions.
-- 💾 **Overlay export** – save PNG overlays blended with the source image for reporting or further editing.
-- ⚙️ **Config file defaults** – populate `config.toml` to ship different starting values across machines.
-- 🎨 **Preset palette** – one-click access to common colours (red, cyan, grey, black, …).

-## Getting Started
-
-### Requirements
-
-- Python 3.11+ (includes the standard `tomllib`; for 3.10 install `tomli`)
-- Tkinter (ships with most Python distributions; on Linux install `python3-tk`)
-- Pillow (`pip install pillow`)
-
-### Installation
+## Requirements
+- Python 3.11+ (3.10 works with `tomli`)
+- [uv](https://github.com/astral-sh/uv) for dependency management
+- Tkinter (install separately on some Linux distros)
 
+## Setup with uv
 ```bash
-git clone https://github.com/<your-org>/ColorCalc.git
-cd ColorCalc
-python3 -m venv .venv
-source .venv/bin/activate  # Windows: .venv\Scripts\activate
-pip install -r requirements.txt  # or pip install pillow
+git clone https://github.com/<your-org>/ICRS.git
+cd ICRS
+uv venv
+source .venv/bin/activate         # Windows: .venv\Scripts\activate
+uv pip sync                       # installs Pillow + optional deps from pyproject
+uv run icrs                       # launches the GUI
 ```
-
-### Launch
-
+To include the optional ttkbootstrap theme pack:
 ```bash
-python3 main.py
+uv pip install '.[ui]'
 ```
 
-The window opens maximized; load an image, tweak sliders, and watch the overlay update in real time.
-
----
-
-## Usage Tips
-
-- **Pick colours quickly:** use the 🎨 button to open a colour chooser or click directly inside the left preview (enable 🖱️ first).
-- **Fine-tune defaults:** edit `config.toml` and set keys under `[defaults]`. Restart the app to apply changes.
-- **Reset & compare:** `🔄 Slider zurücksetzen` reverts to defaults and clears the status message.
-- **Exclude areas:** right-drag on the original preview to mark rectangles; use `↩️` to undo or `🧹` to clear all.
-- **Copy stats:** right-click the filename or ratio labels to copy.
-- **Export overlay:** `💾` saves a PNG with your overlay merged onto the source image.
-- **Theme switch:** `🌓` toggles between light/dark; button palettes update instantly.

-## Configuration (`config.toml`)
+## Workflow
+1. Load an image (`📂`) or a folder (`📁`).
+2. Pick a colour (`🎨` dialog, `🖱️` image click, or preset swatch).
+3. Fine‑tune sliders; watch the overlay update on the right.
+4. Move through folder images with `⬅️` / `➡️`.
+5. Draw exclusions with right drag; reset or save when ready.
 
+## Config Defaults
+Optional `config.toml`:
 ```toml
 [defaults]
-hue_min = 250.0  # 0..360°
+hue_min = 250.0
 hue_max = 310.0
-sat_min = 15.0   # percentage 0..100
+sat_min = 15.0
 val_min = 15.0
 val_max = 100.0
-alpha = 120      # overlay opacity 0..255
+alpha = 120
 ```
 
-All values are optional; omit them to fall back to built-in defaults. Hue min/max support wrap-around (e.g. 350 to 20).
+## Project Layout
+```
+app/
+  app.py          # main app assembly
+  gui/            # UI, theme, picker mixins
+  logic/          # image ops, defaults, reset
+config.toml       # optional defaults
+main.py           # entry point
+```

-
-## Development Workflow
-
-- Format: project sticks to standard Python style; no formatter enforced.
-- Testing: primary quick check is compilation via `python3 -m compileall app main.py`.
-- Platform quirks: some theme detection uses Windows registry; errors are swallowed when unavailable.

-## Contributing
-
-1. Fork + clone.
-2. Create a feature branch.
-3. Make changes and run `python3 -m compileall app main.py`.
-4. Submit a PR with a clear description and screenshots if UI changes are visible.
