Get the image into Photoshop, get an Adjustmentlayer over it, adjust it that the green part will be white:

Adjustment Layer

Get only the part which was green to be visible for the adjustment layer:

White Adjustment fill

To get there, use the Quick Selection Tool to select the green part of the Bottle.

quick selection tool Selected

Then inverse the selection to get everything else but the green part.

Inverse

Now (if not selected, select the Adjustmentlayer) and hit alt+backspace (on a mac) and the Adjustment Layer only applies to the white area, not the black one.

Cut out

Doubleklick on the Adjustment Layer to get to its settings. Set the controllers like in the image. Now it could look like that, with a little bit more tweaking its even better ;)

I am totally newbie to photoshop. I added Adjustment Layer. After that I am not able to follow what you are saying. Can you please show simple detailed steps? Thanks! –  meetpd Nov 21 '11 at 12:01
    
I hope this helps, with tweaking i mean to get the borders of the green part in the Adjustmentlayer more soft and the white more brighter, eventually with an other Adjustment layer and the same layer mask. –  ueberkim Nov 21 '11 at 12:20
    
Excellent. I will try out and let you know. Thanks a ton! –  meetpd Nov 21 '11 at 12:27
    
awesome technique! This technique is very usefull, since i only copy the part and do HUE/SATURATION.. –  user13330 Jun 13 '13 at 7:21

Good answer by Kimchen, except you could try omitting the quick selection and inverse steps if you select the targeted adjustment tool next to the Master drop down:Screenshot
Then 'Ctrl + click + drag' over the neck (the eyedropper tool should appear) area you want to replace. The hues will change dragging left or right. Experiment with hue changes, then increase the lightness to 100% this will then reproduce the effect Kimchen described. Any other color other than white is easy to replace!

Also google the 'Color Range' option under the 'Select' menu to check if this could assist you.

Thanks.
