Because you must use the openPicker function like this: 
openPicker ( "Car color", "#FFFFFF", "Car color changer" )

thanks.

Because is not magic, the color picket triggers a event when click 'ok'.

addEvent ( "onColorPickerOK", true ) 
addEventHandler ( "onColorPickerOK", root, 
    function ( id, hex, r, g, b ) 
        if ( id == "Car color" ) then 
                   -- Code to set vehicle color. 
        elseif ( id == "Headlight color" ) then 
                     -- Code to set headlight color. 
        end 
    end 
)
