onclick

Me and a friend are making an app right now and came up to the part to where we want to make it change color or change the lighting on a button when you click on it and the only thing that we can find that there is to work with is the onClick command, and i'm being told that we would have to call upon that and then have it show the new pic and that start whatever command the button originally has to begin with a millisecond later. I thought that there was a way to make it show the new pic when holding the button down and then when released it would then do what the button is suppose to do. Any suggestions on how to accomplish this?
