Create a simple interactive coloring application with the following features: 

### Project Overview
- An application allowing users to select images and color distinct areas.
- Support common image formats such as JPEG and PNG.

### UI/UX Design and Flow
- **First Screen**: 
  - Display a prominent button labeled "Select Image from Computer."
  - On button click, open a file browser for image selection.
- **After Image Selection**: 
  - Show a centered preview of the selected image on the screen.
  - Display a button below it labeled "Start Coloring."
- **Start Coloring Screen**:
  - Parse the image to detect at least two colorable areas, displaying the image fullscreen with detected boundaries.
  - **Top-left Corner**:
    - "Back" button: Returns to image selection with a confirmation prompt.
    - "Save" button: Downloads the colored image.
  - **Top-right Corner**:
    - Large red circle indicating the current selected color, default being bright blue.
    - On click, open a fullscreen palette with 24 vibrant colors arranged in a circular layout; close palette upon color selection.

### Core Functionality and Logic
- Implement boundary detection to identify colorable areas.
- Allow tap/click filling for coloring interaction within boundaries with the selected color.
- Ensure support for image types like JPEG and PNG for reliable coloring parsing.

### Best Practices
- Handle errors by displaying a message "Oops! We couldn't find areas to color in this image. Please try another image with clearer outlines," if fewer than two areas are detected.
- Ensure intuitive navigation and prompt confirmation for actions like going back.
- Maintain interactive and responsive design with easy transitions between screens.

Create a simple interactive coloring application:

First screen:
- Display a prominent button labeled "Select Image from Computer."
- Upon clicking, open file browser to let the user select an image.

After selecting an image:
- Show a preview of the chosen image centered on the screen.
- Below the preview, display a button labeled "Start Coloring."

After clicking "Start Coloring":
- Attempt to parse the image to detect at least two distinct areas suitable for coloring.
- If successful, display the image fullscreen vertically with detected boundaries.

Top-left corner:
- "Back" button: returns to image selection after confirmation.
- "Save" button: downloads the colored image.

Top-right corner:
- Large red circle indicating the current selected color (default bright blue).
- On click, open fullscreen palette with 24 vibrant colors arranged in circles. Close palette upon selection.

Coloring interaction:
- Detect boundaries automatically.
- On tap/click within boundaries, fill the area with the selected color.

Error handling:
- If fewer than two colorable areas are detected, display an error message:
  "Oops! We couldn't find areas to color in this image. Please try another image with clearer outlines."
