# Color Separator
This project is a Java Swing application built with NetBeans IDE that separates an input image into its individual color channels (RGBA or CMYK), with options for contrast adjustment, color inversion, and colored/grayscale outputs.
## Features
- **RGBA & CMYK Separation**
- Extract Red, Green, Blue, and Alpha channels
- Extract Cyan, Magenta, Yellow, and Black channels
- **Contrast Adjustment**
- Interactive slider from –255 to +255 for fine-tuning
- **Invert Toggle**
- Invert channel values
- **Colored vs Grayscale Output**
- Display each channel in its native color or as monochrome
- **Drag & Drop UI**
- Process multiple PNG/JPG/JPEG files at once by dragging onto the window
- **Automatic Naming**
- Outputs prefixed with `RGBA[invert,colored]_color_channel` or `CMYK[invert,colored]_color_channel` plus channel name
## How to Use
1. **Run** the provided executable `ColorSeparator.jar`
2. Adjust the **Contrast** slider and toggle **Invert** / **Colored** as desired.
5. Select **RGBA** or **CMYK** channels using the side buttons.
6. Drag and drop one or more PNG/JPG/JPEG files onto the main window.
7. Wait for processing; the UI will briefly display “Images Generated” before resetting.
8. Find the separated channel images saved next to the originals.
