i tried with making alpha content a = 0; this if fadding the button itself.i just want the color inside the gui button to fade and fade out

      function OnGUI()
         {
GUI.backgroundColor.a = Mathf.Lerp(1.0, 0.0,Time.time*0.1);
if(GUI.Button(new Rect(Screen.width *(4.1/6.55), Screen.height*(0.8/6.55),Screen.width*(.4/6.55),Screen.height * (.2/6.55)),""))
        {

         }

         }

GUI.backgroundColor is your answer, I think. for Javascript `GUI.backgroundColor.a = ...` and for C# `GUI.backgroundColor = new Color(r, g, b, a);` (or store it before, so you're not using `new` in OnGUI code)

how to get the effect suppose my button is blue color i want the blue color to fade in and out with out fading the text inside the button. i tried this code GUI.backgroundColor.a = Mathf.Lerp(1.0, 0.0,Time.time*0.1); it is fading the the text along with the gui button color

Not sure what to say. I threw only the first two lines into an OnGUI function and it worked. Then I threw in the bit with the Lerp just to test and... it's keeping the text there while changing the alpha of the button itself. Your button isn't saying anything right now but the color fading should still work..

Try something like GUI.backgroundColor = Color(0, 0, 1, Mathf.Lerp(1, 0, Time.time*0.1)); for the heck of it - see if that makes a difference. Not sure what to say otherwise.

add a label with the same position and set the alpha channel to 1

function OnGUI()
{
    var rect = new Rect(Screen.width *(4.1/6.55), Screen.height*(0.8/6.55),Screen.width*(.4/6.55),Screen.height * (.2/6.55));
    GUI.backgroundColor.a = Mathf.Lerp(1.0, 0.0,Time.time*0.1);
    if(GUI.Button(rect,""))
    {
        Debug.Log("click");
    }

    GUI.backgroundColor.a = 1;
    GUI.Label(rect,"Button");

}
