You must not focus on this special test image. I created it to simply give others a fast way to reproduce. Taking any raw image the effect shown can be created. In my understanding the readings for hue and saturation should be independent of they way I get them into the panel. Using the eyedropper should give me the starting point for a further edit with the slider.
Actually using the eyedropper to achieve the readings mentioned in my first post gives a different color of the image compared to entering the same readings by using the slider. In my understanding this should not be the case.
