[Help] What's wrong with this?

[szskill]

I've checked almost everything, but it just doesn't work.

extern crate colored;

use colored::*;

fn main() {
    println!("abc123".green());
}

Somehow it only works with formats.

println! only takes string literals as the first argument.

// shouldn't compile
let s = "hello";
println!(s);

// should compile
println!("hello");
