It seems that boxplot function doesn't accept TeX Markup to give a specific color to labels of boxplot.

Any idea to give a color to a label using boxplot function?

boxplot([1 2 3 4], 'labels', {'a'}); % make 'a' red

They're just XTickLabel values; set as desired as with any other axes.

For some reason TMW hasn't made a color property for them (yet); is a worthwhile extension request.

boxplot([1 2 3 4], 'labels', {'a'});
hAx=gca;
hAx.XAxis.TickLabelInterpreter='tex';            % make sure interpreter set
hAx.XTickLabel(1)={['\color{red}' hAx.XTickLabel{1}]}; % make 'a' red

Or, of course, you can embed the TeX string in the call if you create the axes first to set the 'Interpreter' property and if boxplot doesn't clear it internally (that I don't know, didn't test).

Correct, I'd already fixed the typo...don't recall just when I noticed it.

The key point was trying to make is that you can retrieve the already-set tick labels (or tick values) and apply the fixup to them instead or recreating the values. This may (or may not) in a given instance be of real savings just depending.
