What is your goal ?
You want to have a list of colors(gray-values) which are used inside the Image ?
After this you want to replace each by a kind of colorpicker by a new (chosen) color-value ?

You know when a color image is converted into a grayscale one there is information loss, hence, generally speaking there is no exact way to restore the original colored one. However you may find 'colorazing' algorithms that could be useful for some specific purposes (that's up to you, of course).
