4.6 UI.Changing children transparency along with parent's

Well, is there any way to link the color.a of all children of the object to it’s parent ?

For example we have a parent with Image(script) and lots of children also with Image(script) components. And i wan’t to make them fade out through transparency using Animation. Is there a way by changing parent’s color.a change the color.a of all of his children not accessing them directly like Child1.Image.color.a…ChildN.Image.color.a.


Or the only one solution is a script ?

Add Canvas Group component to your UI element. There is Alpha parameter. If you change this alpha, it will change transparency of all children UI elements.
