To demonstrate higher resolution in a smaller data set which has 4096 distinct colors -- 16 levels of RGB And for its dithering is gamma adjusted.
I took the image from https://wallpaperaccess.com/nature-landscape, and I use photoshop to resize it into 360x360 picture and saved it as 24-bit BMP. I used HxD editor to copy hexadecimal contents of it to be pasted into notepad++ to eliminate spaces between hex values, then I copied them into Scratch 2 (Scratch 3 is still not good for a quick data processing) to produce dithered image as output which consist to hexadecimal digits of every color components to be pasted into this project.
