Dither it! VS GSAP

Maybe it will be overkill for flags, but you can try with dithering algorithms, where you can select which color you want to keep: Https://ditherit.com/ Https://github.com/noopkat/floyd-steinberg. Source: over 1 year ago

ImageMagick can do anything, but it's a commandline program. There may be some websites that dither images for you - https://ditherit.com/ is one. (I also wrote a program years ago that is excellent at color reduction and dithering, but it's not currently usable.). Source: over 1 year ago

It’s called dithering. Instead of using many different colors you just choose a few and make the best of it. With using six colors (red, green, blue, yellow, white, black) any color can be matched. You can try it out with this tool: https://ditherit.com/. Source: almost 2 years ago

I used https://pixelartselfie.com/en. I later found https://ditherit.com/ which offers more features so I’ll probably do more works. Source: almost 2 years ago

This direct manipulation allows you to leverage robust animation libraries like GSAP or Anime.js, which require direct DOM access to perform optimally. - Source: dev.to / 14 days ago

I've been looking for a small project to do that would let me play with Greensock (GSAP), specifically a bit with some SVG files I generated with Corel Vector. When I saw the frontend challenge and had an afternoon at work with downtime between a few projects, I knew it'd be a great opportunity to explore a bit! - Source: dev.to / about 2 months ago

The GreenSock Animation Platform (GSAP) is a web animation library that provides the logic for adding animation to any site powered by JavaScript. React, being built on top of JavaScript, falls under this category. GSAP is an extremely fun animation tool to use because it offers a great deal of flexibility, you can animate anything using GSAP — texts, images, scroll actions, SVGs, UI interactions, anything! - Source: dev.to / 5 months ago

You can add any animation to any web site. You can use a library like https://greensock.com/gsap/ which seems to be the standard these days. Source: 8 months ago
