If you're working with grey images in Java and want to introduce subtle colors without making drastic changes, this guide is for you. Enhancing grey images with a touch of color can make them more appealing while maintaining their original integrity. Here, we'll explore a method that allows you to add just the right amount of color.

Understanding Color Combination and Scheme

Output: Finally, the modified image is written back to disk.

Benefits of Subtle Colorization

Aesthetic Appeal: Adds a soft touch of vibrance without overwhelming the original image.

Focus: Helps in directing viewer's attention to specific parts of the image.
