How to set BackColor in a TextBox on Web form programmatically?

I want to set the backcolor of a web form programmatically at run time (so the user can select his or her preferred color).

I can do this with a named color, as in:

txt1.BackColor = System.Drawing.Color.PeachPuff;

but I am having a hard time figuring out how to set the color using the RGB value, as in:

txt1.BackColor = SomeConverter("#FEC200");

How is this done?

There was another answer by @Hossein-Narimani-Rad that he deleted that said to use ColorConverter.ConvertFromString. I tried it and got it to work like this:

System.Drawing.ColorConverter conv = new System.Drawing.ColorConverter();
txt1.BackColor = (System.Drawing.Color)conv.ConvertFromString("#FEC200");

But @Win 's and @Manish-Mishra 's answers are more concise and what I am going with.

use this

txt1.BackColor = System.Drawing.ColorTranslator.FromHtml("#FEC200");

also, if you want to convert the System.Drawing.Color back to string(to save in db), do this:

private static String ConvertToHex(System.Drawing.Color color)
{
    return "#" + color.R.ToString("X2") + color.G.ToString("X2") + color.B.ToString("X2");
}

private static String ConvertToRGB(System.Drawing.Color color)
{
    return "RGB(" + color.R.ToString() + "," + color.G.ToString() + "," + color.B.ToString() + ")";
}
