How to implement ColorMap into bar plot ?

I want to create a barplot with the colorcode [0 0 0.8]. How do i do that.

Current code:

figure(1) subplot(3,1,1) bar(-200:1:200,center_rel_01,'r'); grid on ylabel('Rel. Peak Area','FontSize',12,'FontWeight','bold') xlabel('m/z','FontSize',15,'FontWeight','bold') xlim([-200 200]) ylim([0 0.3]) h = legend('2a: NaCl pure');

color 'r' should now be changed in 'Color',[0 0 0.8] somehow?

Thanks
