Color Scheme

Why the dark background?  Because when I created Mood Sentry I knew that I would spend a lot of time composing essays and other types of entries.  I was concerned about battery life, so I decided set the background color to black to save battery life.  Why the fade from blue to yellow?  It's kind of hokey, but think of it as blue to sunny.  Note that when a text field is editable the color gradient reverses, going from yellow to blue.  Did you notice that effect?
