I have plotted some logarithmic curves using LogLogPlot.

In this case, I wanted to add two vertical lines to the plot; I used Epilog, but it seems that it does not work with LogLogPlot. Instead, I used GridLines. But now, the problem is that I cannot allocate two colors for my lines. Only the first color works.

Why is that?


 GridLines -> {{1, 8}, None}, 
 GridLinesStyle -> {{Directive[Black, Dashed]}, {Directive[Red}}

Here is an example: I want to add several vertical lines in different colors. enter image description here

LogLogPlot[{Log[x]^x, x^x}, {x, 0.1, 10}, PlotLabels -> "Expressions",
  GridLines -> {{{1, 
     Directive@{AbsoluteThickness[2], Green, Dashed}}, {8, 
     Directive@{Opacity[1], AbsoluteThickness[2], Red, Dashed}}}, None}
 ]
