HexColor::lighten(f32), darken(f32), brightness(f32)

Similar to the CSS rules for lighten, darken, brightness.

Because this is too annoying:

        // Lighten 20%
        const LIGHTEN_AMT: f32 = 1.2;
        let (r, g, b, _a) = HexColor::from_u24(0x66bbff).split();
        let (r, g, b) = (
            (r as f32 * LIGHTEN_AMT).max(u8::MAX as f32) as u8,
            (g as f32 * LIGHTEN_AMT).max(u8::MAX as f32) as u8,
            (b as f32 * LIGHTEN_AMT).max(u8::MAX as f32) as u8,
        );
        HexColor::from_u24(
            (0xff & r as u32) << 16
                | (0xff & g as u32) << 8
                | (0xff & b as u32),
        )

Printing defaults

Hey! I thought this was abandoned. Thanks for getting around to it all!

Currently println!("{}", my_color) will print #RRGGBB
Currently println!("{:?}", my_color) will print #RRGGBBAA

I'm not satisfied with how this works. For one, {:?} is supposed to be a debug print. This is standard across Rust. If you rely on the current behavior, it would confuse a code reviewer what's actually going on here.

I was going to suggest next to set the default Display to print the full color: #RRGGBBAA
And use #[derive(Debug)] to handle the debug print, as one would expect.

To maintain functionality, we could add sugary functions for more readability/context:
color.rgb_str() and color.rgba_str()

[Feature Request] Color Inversion

Feature Request

• I would like to work on this feature!

Lovely library! I just made a function that naively inverts colors and I'd like to add it as a method to the main struct

const fn invert_color(color: HexColor) -> HexColor {
    let r = 0xFF - color.r;
    let g = 0xFF - color.g;
    let b = 0xFF - color.b;
    HexColor::new(r, g, b)
}

Maybe later I can implement a gamma corrected invert function.

Do you think this is a good idea? If not, I don't mind if you close this.

[Feature Request] Alpha support

Hi, thanks to the library! It helps get things done easily.

Currently alpha channel is not supported yet, is there any plan to work on it?
