What you should remember is that the rule of not clipping the histogram is more of a guideline - sometimes it's ok to even clip in the highlights, if you're making a purposefully high key photo, or if the sun is in the frame. In most cases it's ok to clip in the shadows, where it's hardly noticable - in fact I frequently up the black point a bit to add more punch, without looking at whether the histogram clips. My rule of thumb is that shadow clipping just happens, but highlight clipping should only happen when you want it to.



That said, it is concievable that you could have a tone with, in this case, just a slight bit of blue in it, where if you cut the blue out you end up with a slightly different tone in the darker areas. Whether and how much this happens depends entirely on what tool you use for your adjustments, some are very coarse and some are very sophisticated. But in general, you should let go of the illusion that the histogram is telling you how good the picture is and just look at the picture. The histogram can point you at potential problems, but in the end it's how the picture looks that matters. Your viewers will not have a histogram at hand to judge the picture by, after all
