First make sure you have Color Finesse installed (Free with AE 6.5 and 7) and use that. It’s a modern color corrector. AE only has old school Photoshop-like coloring tools. But if you don’t use color finesse, you can just stack a hue/sat with a curves and do it all there. Use the hue sat to control the saturation and the RGB curve for your levels and the individual color channel curves (Red, Green, Blue) for your hue offsets.
