matching colours

Hi,
I have photographed a label, using two different settings on my camera. The label is supposed to be black and white, but one of the settings produced an image which has a somewhat yellowish-orangish tint.
The dropper tool tells me that the composition is:
Red ...... 164
Green ... 92
Blue ..... 42
I would like to change this colour (above) to the same as my white label, which reads:
Red ...... 157
Green ... 119
Blue ..... 98
Is there a way of doing this?
Thanks,
...... john

you can use color balance to adjust...

Hi Antonio,
There's no way of plugging the RBG values I want into an app that will allow me to use the spray or fill tool to change the colour?
Thanks for replying.

Click on the box as shown in 1. A window opens. Enter the correct values in the RGB boxes (2)

If I understood the question correctly....

Hi Antonio,
I wasn't able to find a way of applying Patrick's suggestion.
I thought it would be simple thing to apply the RGB readings from one label to the RGB readings of the other label. It seems I was wrong.
Basically, what I want to do, is replace the tinted area (which should be white) in the photograph of a black and white label with the same shade of white from another photograph. The colour replacement feature works, but does make subtle intensity variations. The histogram seems to do it, but I haven't found a way of applying the colour from one label to the other label.

Hi Tom,
It's going to take some time for me to digest all of this.
Thanks for your help,
