So although I can see in the helpful examples you've posted have improved on the previous darkening contast and the previous too solid-quality to the saturation to me via my laptop screen they still appear too red(!!)

No color correction was done on my examples except some desaturation on the last pic, the first step is to set the correct black and white point before you even attempt to color correct anything because it will greatly affect how your colors will come out, my examples weren't anything definitive, I just wanted to demonstrate how much a subtle contrast correction can do. If you've only seen my disc on your laptop you haven't seen it at all.
