You can make extension to just change one color component

static class ColorExtension
{
    public static Color ChangeG(Color this color,byte g) 
    {
        return Color.FromArgb(color.A,color.R,g,color.B);
    }
}

then you can use this:

  yourColor = yourColor.ChangeG(100);

You must use Color FromArgb method to create new color structure  var newColor   Color FromArgb 0xCC 0xBB 0xAA

You could create a color using the static FromArgb method   Color redColor   Color FromArgb 255  0  0     You can also specify the alpha using the following overload

You could do   Color c   Color FromArgb red  green  blue     red  green and blue are integer variables containing red  green and blue components

The Color structure is immutable  as all structures should really be   meaning that the values of its properties cannot be changed once that particular instance has been created   Instead  you need to create a new instance of the structure with the property values that you want  Since you want to create a color using its component RGB values  you need to use the FromArgb method   Color myColor   Color FromArgb 100  150  75
