Christina: I took your #4 did a small crop, however first I opened in ACR or if you use LR, did some adjustment but nothing much, small changes. When into the colours sections and adjusted to bring out those pinks that I knew were there. They probably were not strong but I think, no, I know my mind would have remembered as they now appear as that is how I want them to appear.
Christina what you see and the camera sees are two different things, the trick is to take what the camera captured and change that into what your mind saw. That is where knowing what can be done in post production, it took me about 3 minutes in total. I knew that the pink was there so it was a matter of bring that colour forward to give me my reality. I would suggest when working with the colour slider to be bold making big moves to see what happens, small ones sometimes one does not see the change.
