Well you can get all the controls from the Page. so when you get the controls by their type you can change their color.
Here is a link which explains how you can do it:
Get all controls in web page[^]
A similar code will be:

C#

public void GetUserControls(ControlCollection controls)
{
    foreach (Control ctl in controls)
    {
        if (ctl is UserControl)
        {
            // Do whatever.
        }

        if (ctl.Controls.Count > 0)
            GetUserControls(ctl.Controls);
    }
}

And you can use it as:

C#

GetUserControls(Page.Controls);

Good luck,
OI

Solution 2

A for loop will be resource intensive i would suggest

C#

//will return all Controls in  ctrlToSearch.Controls whose name is nameofControl
private Control[] FindControlsByName(Control ctrlToSearch, string nameofControl)
{
return ctrlToSearch.Controls.Find(nameofControl, true);
}
