Here is the Easiest way, No Helpers, No Converters, No weird Media references. Just 1 line:

System.Drawing.Brush _Brush = new SolidBrush(System.Drawing.Color.FromArgb(this.ForeColor.R, this.ForeColor.G, this.ForeColor.B));

Brush brush = new SolidColorBrush(color);

The other way around:

if (brush is SolidColorBrush colorBrush)
    Color color = colorBrush.Color;

Or something like that.

Point being not all brushes are colors but you could turn all colors into a (SolidColor)Brush.

I had same issue before, here is my class which solved color conversions Use it and enjoy :

Here U go, Use my Class to Multi Color Conversion 

using System;
using System.Windows.Media;
using SDColor = System.Drawing.Color;
using SWMColor = System.Windows.Media.Color;
using SWMBrush = System.Windows.Media.Brush;

//Developed by امین امیری دربان
namespace APREndUser.CodeAssist
{
    public static class ColorHelper
    {
        public static SWMColor ToSWMColor(SDColor color) => SWMColor.FromArgb(color.A, color.R, color.G, color.B);
        public static SDColor ToSDColor(SWMColor color) => SDColor.FromArgb(color.A, color.R, color.G, color.B);
        public static SWMBrush ToSWMBrush(SDColor color) => (SolidColorBrush)(new BrushConverter().ConvertFrom(ToHexColor(color)));
        public static string ToHexColor(SDColor c) => "#" + c.R.ToString("X2") + c.G.ToString("X2") + c.B.ToString("X2");
        public static string ToRGBColor(SDColor c) => "RGB(" + c.R.ToString() + "," + c.G.ToString() + "," + c.B.ToString() + ")";
        public static Tuple<SDColor, SDColor> GetColorFromRYGGradient(double percentage)
        {
            var red = (percentage > 50 ? 1 - 2 * (percentage - 50) / 100.0 : 1.0) * 255;
            var green = (percentage > 50 ? 1.0 : 2 * percentage / 100.0) * 255;
            var blue = 0.0;
            SDColor result1 = SDColor.FromArgb((int)red, (int)green, (int)blue);
            SDColor result2 = SDColor.FromArgb((int)green, (int)red, (int)blue);
            return new Tuple<SDColor, SDColor>(result1, result2);
        }
    }

}

It's often sufficient to use sibling's or parent's brush for the purpose, and that's easily available in wpf via retrieving their Foreground or Background property.

If you happen to be working with a application which has a mix of Windows Forms and WPF you might have the additional complication of trying to convert a System.Drawing.Color to a System.Windows.Media.Color. I'm not sure if there is an easier way to do this, but I did it this way:

System.Drawing.Color MyColor = System.Drawing.Color.Red;
System.Windows.Media.Color = ConvertColorType(MyColor);

System.Windows.Media.Color ConvertColorType(System.Drawing.Color color)
{
  byte AVal = color.A;
  byte RVal = color.R;
  byte GVal = color.G;
  byte BVal = color.B;

  return System.Media.Color.FromArgb(AVal, RVal, GVal, BVal);
}

Then you can use one of the techniques mentioned previously to convert to a Brush.

you can use this:

new SolidBrush(color)

where color is something like this:

Color.Red

or

Color.FromArgb(36,97,121))

or ...

This is for Color to Brush....

you can't convert it, you have to make a new brush....

SolidColorBrush brush = new SolidColorBrush( myColor );

now, if you need it in XAML, you COULD make a custom value converter and use that in a binding
