```rust let c = csscolorparser::parse("rgb(100%,0%,0%)").unwrap();

asserteq!(c.rgba(), (1., 0., 0., 1.)); asserteq!(c.rgbau8(), (255, 0, 0, 255)); asserteq!(c.tohexstring(), "#ff0000"); asserteq!(c.torgb_string(), "rgb(255,0,0)"); ```

Using parse() method on string.

```rust use csscolorparser::Color;

let c = "#ff00007f".parse::().unwrap();
