plot(rand(10,4))                  % plot 4 lines in default color cycle
legend('a', 'b', 'c', 'd')        % label them -- colors show automagically
text(2,0.05,'Stuff in green','color','g')  % add some text in a color
You can create custom colors or select the named colors from a list--there are many examples in the doc. See the doc on the various functions above and the links on annotation and enhancement in the Graphics section.
