Colour Saturation Setting?

Hey Guys,

I am on El Capitan and I am using the AMD R9 290 Graphics card. On Windows using the AMD Radeon Software there is a option to increase just the saturation without changing the contrast or brightness. So I am wondering is there a way to do it on El Capitan using some external software. I have tried the built in Color Tool which changes the contrast but it's not what I want.

I am little into saturation and hence its bugging me a little. Any help would be greatly appreciated.
