How to make a color splash photo?

I love strong visual impact. Usually, I take photos with camera apps, such as Camera+, PowerCam, Hipstamatic with my iphone 4S, then edit them with some apps, like Color Splash, snapseed, PhotoFX, PhotoForge2…
How do you make a color splash photo? Recommending me some similar ios apps are much appreciated.

Camera awesome, fast cam

I suggest Fotor to you. It's a photo editor online and it's also available on iPhone. After editing, you can directly save your photo on your computer or put your photo to facebook, flickr or twitter. I've been using it for a period and find it really a nice handy photo editor.

I think you should try their website first, then make a decision whether you should use their app.
