Albano, 1st try (more difficult but precise): Image --> Adjust --> Color Balance (Ctrl+B) and adjust the levels separately for CMY and Hilight/Midtones/Shadows. It's a bit tricky but it works fine.
2nd try (more visual) Image --> Adjust --> Variations, same stuff but with thumbnails and Saturation controls. You can set the unit of variation.
