apply hue/saturation on rectangle fill color

Hi

I use photoshop as a vector tool and need to know if adjustment can be apply to vector shape seelction.

I watch a youtube tutorial where hue/saturation can be apply to selected area using lasso tool and save selection in the channels tab . I try to do the same thing on a rectangle shape  but using warp tool for selection . But when select menu-> Image-> Adjustment -> ( only variation is enable /selectable) . I can't select hue /saturation menu item ?

Is there a way to apply hue /saturation in this case in photoshop CS6 ? .

Can we apply effects ( adjustment setting ) in all shape ( vector)  in photoshop CS6 ?
