I know what I want and I know it exists but I don't how to word it so I can search for it.

I recently restored my phone and I used to have it set up so alert windows (low battery, text etc) were teal, not blue. How do I do this again?

Also, I want a grey/black keyboard. I used to have one and I know it came in other colors but I can't find the thread.

Finally, how do you get the standard windows to change color? It's hard to explain but, the text message window is normally blue and I used to have it grey with teal buttons.

Any ideas?
