We have a mobile app with a regular header (filters, search, etc.) and a results listview at the bottom (fyi the icon to the right is not the real icon).
I like how the app looks and I don't want to change anything, but I want to add some color to the header. I'm including the screenshot of the app. I prefer painting the header and using a lighter tone of the same color in the Search box.
The problem I'm having is that I don't know what colors to add to the header, and I don't want to test. I prefer looking at time-tested alternatives and selecting something from there.
So the other day I thought I had found the perfect combination, as I had seen it in another very-popular mobile app. I've been looking at this combination many times and I was liking it every time. But then today I realized its colors are very similar to facebook. So obviously I won't use them.
I've been searching on the web for examples, but haven't found anything that I like.
How can I select a nice combination of colors without having to test for combinations? Ideally, I would prefer browsing through a mobile app gallery/showcase, but I haven't found any.
What I liked before, but today looks like facebook:
