Return a SolidColorBrush from a custom color string

I have this line and it works but how can i return a custum color string for example "#2228D4"

return (Boolean)value ? new SolidColorBrush(Colors.Red) : new SolidColorBrush(Colors.Yellow);

It's a Windows Phone 8 Application, so I can't use WPF's ColorConverter.

You can make use of the below method to Convert ColorString(hex code) to Color object.

    public Color ConvertStringToColor(String hex)
    {
        //remove the # at the front
        hex = hex.Replace("#", "");

        byte a = 255;
        byte r = 255;
        byte g = 255;
        byte b = 255;

        int start = 0;

        //handle ARGB strings (8 characters long)
        if (hex.Length == 8)
        {
            a = byte.Parse(hex.Substring(0, 2), System.Globalization.NumberStyles.HexNumber);
            start = 2;
        }

        //convert RGB characters to bytes
        r = byte.Parse(hex.Substring(start, 2), System.Globalization.NumberStyles.HexNumber);
        g = byte.Parse(hex.Substring(start + 2, 2), System.Globalization.NumberStyles.HexNumber);
        b = byte.Parse(hex.Substring(start + 4, 2), System.Globalization.NumberStyles.HexNumber);

        return Color.FromArgb(a, r, g, b);
    }

And you can return brush using the below code

(Boolean)value ? new SolidColorBrush(ConvertStringToColor("FFFF0000")) : new SolidColorBrush(ConvertStringToColor("FF00FF00"));

As you're on phone you don't have access to BrushConverter. Do it by breaking the hex down and assigning it to each component instead:

var color = new Color() {R = 0x22, G = 0x28, B = 0xD4};
var brush = new SolidColorBrush(color);

Obviously, keep a reference to brush rather than recreating it over and over :)
