I have written the code below:
ListPlot[das1, PlotMarkers -> {\[FilledCircle], 12}, PlotStyle -> {Black}, Joined -> True, Mesh -> All, MeshStyle -> Red, PlotLegends -> Placed[Style[#, FontSize -> 20] & /@ {"6.7 ps"}, {Top, Right}]] I want a black line to go through my red data points. Then, I want the plot legend to be red.
However, by using the above code I get a black plot legend.

How can I set the plot legend color independent of the plot itself?
How can I extend the solution to multiple graphs in one plot?
