First let me start by the fact that I am mildly color blind. I see basic colors OK but don't ask me to read a resistor color code (I use an ohm meter).
Perhaps that makes me less color oriented than others? Maybe.
That said, I find the various colored bars on the Settings pages quite distracting. Further, there is no legend on each page to explain what the colors represent which makes them less useful. I think its more noise than useful
If there are settings to accentuate, I think bold italics could be better. But still, something on the page should explain the accentuation.
Just my 2-cents worth. It's a MINOR issue. I may be the outlier on this anyway. I can live with that.
