copied!<p>The short way to do it in a tweet:</p> <pre><code>(Color)XamlReader.Load(string.Format("<Color xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation …\">{0}</Color>", c)); </code></pre> <p>The recommended way is to get <a href="http://nuget.org/packages/winrtxamltoolkit" rel="nofollow">WinRT XAML Toolkit</a> from NuGet and call</p> <pre><code>WinRTXamlToolkit.Imaging.ColorExtensions.FromString(c); </code></pre> <p>This runs way faster than using <code>XamlReader</code>, so it is recommended if you need to call it more than once. You can also clone it from <a href="https://github.com/xyzzer/WinRTXamlToolkit/blob/master/WinRTXamlToolkit/Imaging/ColorExtensions.cs" rel="nofollow">GitHub</a> or copy and paste from here:</p> <pre><code>#region FromString() /// <summary> /// Returns a Color based on XAML color string. /// </summary> /// <param name="c">The color string.
