The colours are a representation of the distribution of data. Red represents the poorest results, dark red the bottom, blue the better results, dark blue the best results. There is no intent to suggest bad performances, just that it's the poorest result on the list... 90.2% is the worst result on the list... it gets the darkest red. This is how statistics are presented.
Also, when you talk about 50/50 vs. 90/10.... the point here is that they aren't known as Elite career goalies... These aren't 90% elite career goalies... They might have been elite performances, at the right time, but the discussion the prior pages, including my posting, was do you need an elite career goalie?... and for Final's performances... which I was referencing... about half of the goalies in finals are elite goalies... the rest not. I would suggest that winning goalies, is less than 50% elite goalies for winning the Cup....
