The International Color Consortium (ICC) is like a group of friends who get together to agree on what colors look like. They make sure that colors look the same on different devices, like your computer, your phone, and your printer.
Think of it like everyone wants to agree on what the color blue looks like, but sometimes blue looks different on different screens. The ICC helps to make sure that if someone makes something blue on their computer, it will look the same blue on someone else's computer or when printed out, no matter where they are in the world.
The ICC has rules for how to make colors, how to measure colors, and how to use colors in things like pictures or logos. They help people to use colors in a consistent way so everyone can enjoy them the way they were meant to be seen.
