Did you ever notice that colours that you see when you are taking pictures change in your mind when you think about the place say two or three months later? Add to the mix that your camera will alter those colours depending on your settings. Of course for shooter like myself who shoot RAW and settings in camera to be neutral with minimal contrast, cannot rely of the images for colour accuracy. Yes, you can take a colour checker shot as a reference but that takes the fun out of it.
I don't think that all of the above is necessary a bad thing. It gives me a little bit of creative freedom. I can (and my mind usually does) alter the scene to my liking and give my photographs MY perception or rather MY artistic interpretation of the scene. There is a place for accuracy in photographs but not always so.
