I would like to be able to choose the colors for a multiline plot but I can not get it. This is my code
colors = {'b','r','g'};
T = [0 1 2]';
column = [2 3];
count = magic(3);
SelecY = count(:,column),
plot(T,SelecY,'Color',colors{column});

You cannot specify different colors in multi-column (multi-line) plot() calls.
You can record the handles and set the colors individually:
h = plot(T,SelecY);
for K = 1 : length(h)
set(h,'Color', colors{column(K)});
end
Another approach is use the axes ColorOrder property. See here. (Note: you need RGB color specifications for that approach.)

@Walter Roberson: Thank you very much for your answer. However, your response is not be able to select different colors for the plot (both lines of the code appear with the same one).

That sounds unlikely to be the case, but I do not have access to MATLAB this evening to test it out.
