How do I stop a child objects alpha being set by parent alpha?

[Meltdown]

I find it quite frustrating when I use a button prefab, and I want to set the alpha of the 'normal' state alpha to about 50%.
But this then sets the alpha of all child items of the button.

How do I stop this from happening?

I guess you have a hierarchy like:

- buttontexture + buttonscript
-- icontexture

So when you change the alpha of the parent object it will also effect the child. You can instead change it to:

- buttonscript
-- buttontexture
-- icontexture
