An ICC profile is like a recipe for colors to help make sure all the different devices we use to make and view pictures can agree on what colors they should be. It’s like when you and your friend both separately try to make your mom’s famous chili recipe, but you need to compare your recipes with each other to make sure it turns out the same for both of you. So, the ICC profile helps make sure that the blue crayon looks the same color on your computer screen as it does when it’s printed out on paper. It’s a way to keep everyone on the same page about what colors things should be.
