```rust fn main() { use allcolors::getcolor_hex;
//EXAMPLES:
let color_hex = get_color_hex("aqua").expect("well known color name");
let color_hex2 = get_color_hex("give me something interesting").expect("some random color a4f662");
let color_hex3 = get_color_hex("f20").expect("f00 will return ff2200");
let color_hex4 = get_color_hex("010255001").expect("9 digits will become 0aff01");
println!("aqua is #{}", color_hex);
}
```
