ContourPlot: Setting Global Options for Bar Legend

Question

I'm looking to specify the appearance of contour plots globally in my Mathematica notebook. This is easily done with SetOptions:

SetOptions[ContourPlot, 
BaseStyle -> {FontFamily -> "Latin Modern Math",
FontSize -> 14}];

However, this does not apply to BarLegend:

 ContourPlot[Abs[Gamma[u + I v]], {u, -1.5, 1.5}, 
{v, -1.5, 1.5}, PlotLegends -> Automatic]

I have tried to set global options for BarLegend:

SetOptions[BarLegend, LabelStyle -> {FontFamily 
-> "Latin Modern Math", FontSize -> 14}];

but this seems to have no effect! How can I achieve this?

PS: Using v.10.3.0

Answer 1

Figured it out, the options had to be specified for the ContourPlot itself:

SetOptions[ ContourPlot, 
BaseStyle -> {FontFamily -> "Latin Modern Math", 
FontSize -> 14}, LabelStyle -> {FontFamily 
-> "Latin Modern Math", FontSize -> 14}];

Important: Specifying LabelStyle in your plots will automatically over rule this so the BarLegend will have a different style to the ContourPlot. This was actually the source of much confusion.

Hope this is at least helpful to someone.
