+    To create a colored image, we use individual color channels (Red, Green, Blue) and merge them using `cv2.merge()`.  
+    In this example:
+    - The **Blue channel** is filled with 255 (full intensity).
+    - The **Green channel** is set to 0 (no intensity).
+    - The **Red channel** is also set to 0 (no intensity).
+    
+    The channels are then merged into a single RGB image, which is displayed using OpenCV.
