Hexadecimal colors and the Rust palette Crate

My ongoing Rust tinkering found me wanting to fool around with color manipulation; I'd like to write a color exploration/palette generator web API and front end.

This led me to the palette crate, which I'm pretty sure does everything I need and then some, but because I'm still in "only know enough to be dangerous" mode with Rust, it took me a while to figure out how to instantiate an Rgb struct directly from a web-style #abcdef hexadecimal color string.

TL;DR, you can use the FromStr trait:

Code:

use std::str::FromStr;
use palette::{rgb, Srgb};

let my_rgb: rgb::Rgb<Srgb, u8> = rgb::Rgb::from_str("336699").unwrap()

println!("{:?}", my_rgb);

Output:

Rgb { red: 51, green: 102, blue: 153, standard: PhantomData<palette::rgb::rgb::Rgb> }

rgb::Rgb::from_str() supports strings with a leading octothorpe ("#336699"), and it will also take a &String instead of a literal.
