Lets say

Color color = Color.Blue; // Set this as Global.

Whenever the color is changed, set the color in the Global value (color). When the user reset, clear it or rest the color

Keep the color value in a Global Variable, until the user reset.

Thank you very much for your replies
For the first code sent by Mr. Dinesh Gabhane
I applied it but my exact problem is not just how to color the item during the presentation ,
But I want the element previously selected to change the default color to red color, for example, until the user presses a button to restore the previous settings
This code color element after selected during the show only, but when you open the combo box again note that the color back to the previous color .. Is there a way to solve this topic ???

In the simplest case you can write this in XAML:

I am not sure are you using WPF or normal windows or web forms

Plese check below code
public Form1()
    {
        InitializeComponent();

        comboBox1.FlatStyle = FlatStyle.Popup;

        comboBox1.DropDown += new EventHandler(comboBox1_DropDown);
        comboBox1.DropDownClosed += new EventHandler(comboBox1_DropDownClosed);
    }

    void comboBox1_DropDownClosed(object sender, EventArgs e)
    {
        comboBox1.ForeColor = Color.Red;
    }

    void comboBox1_DropDown(object sender, EventArgs e)
    {
        comboBox1.ForeColor = Color.Black;
    }
