Created attachment 145375 [details] Current design Currently, there are four separator lines, each one of them have a shade of grey, which looks super odd. It would be better if all the lines had the same color. Note: I'm using the default Breeze color scheme and Plasma Style.

This will be tricky to solve because these lines all come from different UI components. Thankfully they all live in plasma framework: The horizontal lines come from PlasmaExtras.PlasmoidHeading The vertical lines come from PlasmaComponents3.ScrollView and the vertical separator SVG So it's feasible to fix them all in one commit.
in that particular design, the line at the right of the scrollbar should definitely be the same color of the bottom footer line, tough i think is actually correct that the line on the left is fainter, it wouldn't communicate well which panel the scrollbar belongs otherwise (i know is usually on the right and that can be assumed, but here is helping of split second unconscious perception)
Well, maybe the top and the bottom lines could have the same color and the scrollbar lines, a different color. Analyzing the picture I posted, the bottom line is #4b4f53; top is #4e545b, left (scrollbar) is #445362, right (scrollbar) is #576673 (not considering the alpha channel. I said that they have different shades of grey, but I think they are semi-transparent lines).
Yeah I think it's reasonable for all of them to have the same color except for the scrollbar's left line, which would be lighter. That wouldn't seem random IMO.
