You can use LINQ-to-XML , so that you can do var doc = XDocument.Load("yourfilepath").

For example if your application is in Windows Forms you can use this

        var doc = XDocument.Load("settings.xml");
        var textboxes = doc.Descendants("textbox");

        foreach(var textbox in textboxes)
        {
            // here you can set as attribute the id of the textbox, i assumed this is it
            var attribute = textbox.Attribute("type");
            if (attribute == null) throw new Exception("Invalid xml file");

            var id = attribute.Value;
            if (!Controls.ContainsKey(id)) throw new Exception("Invalid xml file");

            var colorNode = textbox.Descendants("textcolor").FirstOrDefault();
            if (colorNode == null) throw new Exception("Invalid xml file");

            var backgroundColorNode = textbox.Descendants("bgcolor").FirstOrDefault();
            if (backgroundColorNode == null) throw new Exception("Invalid xml file");

            Controls[id].ForeColor = ColorTranslator.FromHtml(colorNode.Value);
            Controls[id].BackColor = ColorTranslator.FromHtml(backgroundColorNode.Value);
        }

        var button = doc.Descendants("button").FirstOrDefault();
        if (button == null) throw new Exception("Invalid xml file");

        var colorButton = button.Descendants("textcolor").FirstOrDefault();
        var backgroundColorButton = button.Descendants("bgcolor").FirstOrDefault();
        //button1 is the id of the button
        Controls["button1"].ForeColor = ColorTranslator.FromHtml(colorButton.Value);
        Controls["button1"].BackColor = ColorTranslator.FromHtml(backgroundColorButton.Value);

You must add other validations like the color names must be valid if not replace them with a default color or throw an Exception. Also I recommend to use hex format for colors for reliability
