Color-blind casting means that an actor is chosen for a role based only on their talent, not their skin color. It's like when you're playing a game and everyone gets to pick a character. Instead of only letting certain people pick certain characters based on what they look like, everyone gets to pick any character they want. In the same way, color-blind casting lets anyone audition for a role, no matter what they look like on the outside. This is important because it makes sure everyone has a fair chance to succeed and it also helps to break down stereotypes about who can play certain roles.
