Color generation

Color Space

Construct a color from a string. You can use the from_str method to construct a color from a string. Currently supported color spaces are:

• RGB
• RGBA
• HEX
• HSL
• HSV
• Named color from w3cx11

For example:

```rust use color_art::Color; use std::str::FromStr;

let color = Color::fromstr("rgb(255, 255, 0)").unwrap(); let color = Color::fromstr("rgba(255, 255, 0, 0.5)").unwrap(); let color = Color::fromstr("#ffff00").unwrap(); let color = Color::fromstr("hsl(60, 100%, 50%)").unwrap(); let color = Color::fromstr("hsv(60, 100%, 100%)").unwrap(); let color = Color::fromstr("yellow").unwrap(); ```

Random

You can use the random method to construct a random color.

```rust use color_art::Color;

let color = Color::random(); ```

Color conversion

Stringify a color

Stringify a color to a string. You can use the hex, rgb, rgba, hsl, hsv, name method to stringify a color to a string. For example:

```rust use color_art::Color; use std::str::FromStr;

let color = Color::from_str("#ffff00").unwrap(); color.hex(); // "#ffff00" color.rgb(); // "rgb(255, 255, 0)" color.rgba(); // "rgba(255, 255, 0, 1)" color.hsl(); // "hsl(60, 100%, 50%)" color.hsv(); // "hsv(60, 100%, 100%)" color.name(); // "yellow" ```

Color Channel

You can use the red, green, blue, hue, saturation, lightness, alpha method to extract the color channel.

```rust use color_art::Color; use std::str::FromStr;

let color = Color::from_str("#ffff00").unwrap(); color.red(); // 255 color.green(); // 255 color.blue(); // 0 color.hue(); // 60.0 color.saturation(); // 1.0 color.lightness(); // 0.5 color.alpha(); // 1.0 ```

Color Operation

average

You can use the average method to average a list of colors.

```rust use color_art::Color; use std::str::FromStr;

let colors = vec![ Color::fromstr("#ffff00").unwrap(), Color::fromstr("#ff0000").unwrap(), Color::from_str("#0000ff").unwrap(), ];

let averagedcolor = Color::average(&colors); averagedcolor.hex(); // "#aa5555" ```

darken

Decrease the lightness of a color in the HSL color space by an absolute amount.

```rust use color_art::Color; use std::str::FromStr;

let color = Color::fromstr("#ffff00").unwrap(); let darkenedcolor = color.darken(0.2).unwrap(); darkened_color.hex(); // "#999900" ```

lighten

Increase the lightness of a color in the HSL color space by an absolute amount.

```rust use color_art::Color; use std::str::FromStr;

let color = Color::fromstr("#ffff00").unwrap(); let lightenedcolor = color.lighten(0.2).unwrap(); lightened_color.hex(); // "#ffff66" ```
