MATLAB: Bar graphs – color coding..

bar plot color

Hello,
I need to color code my bar graph.
a = [10 20 30 25 15] b = [1 3 2 1 4] bar(a)
BUT, I want a(1) and a(4) the same color because b(1) and b(4) = 1; a(2), a(3) and a(5) each a different color because b(2,3 and 5) are different.
Thanks, S

a = [10 20 30 25 15] 
b = [1 3 2 1 4] 
cl='rgbmc'
for k=1:numel(a)
  bar(k,b(k),cl(b(k)))
  hold on
end
set(gca,'Xtickmode','auto')
set(gca,'Xtick',1:k)
