**Skybrud.Colors** is a small library for working with various color models, currently supporting RGB, CMY, CMYK and HSL. The library features converters for converting back and forth between the supported color models.





## Installation

Install the package via [**NuGet**](https://www.nuget.org/packages/Skybrud.Colors). To install the package, you can use either .NET CLI:

```

dotnet add package Skybrud.Colors

```

or the NuGet Package Manager:

```

Install-Package Skybrud.Colors

```





## Usage

Initialize a new `RgbColor` instance and convert to various string formats and other color models:

```cshtml

@using Skybrud.Colors

@{

    RgbColor navy = new RgbColor(0, 0, 128);

    // Convert to HEX -> #000080

    string hex = navy.ToHex();

    
@hex


    // Convert to CSS -> rgb(0, 0, 128)

    string css = navy.ToCss();

    
@css


    // Convert to HSL -> HSL: 240, 100, 25

    HslColor hsl = navy.ToHsl();

    
@hsl


    // Convert to CMY -> CMY: 100, 100, 50

    CmyColor cmy = navy.ToCmy();

    
@cmy


    // Convert to CMYK -> CMYK: 100, 100, 0, 50

    CmykColor cmyk = navy.ToCmyk();

    
@cmyk


}

```

Get the WCAG contrast ratio between two instances of `RgbColor`:

```cshtml

@using Skybrud.Colors

@using Skybrud.Colors.Html

@using Skybrud.Colors.Wcag

@{

    // Get colors from the constants in the "HtmlColors" class

    RgbColor red = HtmlColors.Red;

    RgbColor blue = HtmlColors.Blue;

  

    // Calculate the WCAG contrast ratio

    double ratio = WcagHelpers.GetContrastRatio(red, blue);

    
WCAG ratio: @ratio


}

```

Get a list of hex colors representing gradient steps between two hex colors:

```cshtml

@using Skybrud.Colors

@{

    //Get gradient colors Blue to Red

    var colors = Skybrud.Colors.ColorUtils.GetGradientColorsHexCodes("#0000ff", "#ff0000", 10); 

   

        
Start: #0000ff | End: #ff0000
  

        @foreach (var color in colors)

        {

            
@color

        }    

}

```
