How to make a complex color image clear

Quick answer：

To make a complex color image clearer, you can use image enhancement techniques such as sharpening, contrast adjustment, and noise reduction. Software like Adobe Photoshop, GIMP, or dedicated photo editing apps offer these features. Additionally, upscaling the image with algorithms that focus on edge detection and detail enhancement can help improve clarity. It's important to be careful not to over-process the image, which can lead to artifacts.
