I'm plotting some data within a for loop using the following code:

for k = 1:13 % there is some code here to loop through some files
     Y = {'Intensity T=10','Intensity T=15','Intensity T=20','Intensity T=25','Intensity T=30','Intensity T=35','Intensity T=40','Intensity T=45','Intensity T=50','Intensity T=55','Intensity T=60','Intensity T=65','Intensity T=70'};
     fig1 = figure('name',Y{k},'numbertitle','off');
     for ij = 1:6
        x = 0:0.2:9.6;
        plot(x,fliplr(totalinmodesarray),'k.--'); % Additional plot in specified colour
        y = fliplr(intensitymatrix(ij,2:2:end));
        intensities{ij} = y; 
        plot(x,y,'.--')
        xlabel('Current (mA)')
        ylabel('Power (mW)')
        hold on
     end
     legend('Total','mode 1', 'mode 2', 'mode 3', 'mode 4', 'mode 5', 'mode 6','Location','best')
     saveas(gcf, Y{k}, 'fig')
end

This simple way of doing the legend worked fine until I added in another plot that I wanted to be in a specified colour rather than the default matlab colours. This gave me the wrong colours in the legend labels, such that several of them didn't match the lines. Do I need to incorporate the legend into the loop to solve this?
