How to use two different color schemes in one bar chart?

I want to put different color schemes to represent X and Y in the bar chart. I am trying to do it with colormap but unable to do it. I am getting something like this

But I want something as put one figure on the top of second.

X = [15,12,11
       18,17,13
       19,18,16
       15,15,15
       14,13,12];
   Y = [5,2,1
       8,7,3
       9,8,6
       5,5,5
       4,3,2];
  figure
  wi=1;
  bar(Y, wi);
  colormap(cool)
  hold on
  bar(X, wi/4);
  colormap(summer)
  legend('One','Two', 'Three');

figure
wi=1;
ax1 = subplot(2,1,1);
bar(Y, wi);
colormap(ax1,cool)
legend('One','Two', 'Three');

ax2 =  subplot(2,1,2)
bar(X, wi/4);
colormap(ax2,summer)
legend('One','Two', 'Three');

@KL Thank you for your reply but I want something like the mentioned figure (created using Microsoft Excel). Here Series1, Series2, and Series3 represent X while Series4, Series5, and Series6 show Y. I would appreciate, if I get Series4, Series5, and Series6 over Series1, Series2, and Series3 respectively. I hope my query is now more clear.

Please Note I can get such figure by joining X and Y both matrices. I will be able to use one colormap using this way. But I want to use two different colormaps or color schemes.

Oh ok. You just need to plot X and Y in the same plot and apply the new colormap.

figure
bar([X Y],1) %plotting X and Y together - 6 coloumns
cmap = [cool(3); winter(3)]; %create the colormap 3 from cool, 3 from winter
colormap(cmap); %apply
legend('Series1','Series2', 'Series3','Series4','Series5', 'Series6');

@KL, I really appreciate your efforts.

I tried the following code.

bar(X, 0.25) 
hold on
bar(Y, 1) 
legend('Series1','Series2', 'Series3','Series4','Series5', 'Series6');

And I got the following output

Now I want to use two different color schemes for both X and Y as it is impossible to distinguish between series1 and series4.

Sorry for inconvenience.

Did you try the code I gave you? It looks just like your Excel figure.

@KL, I tried your code and working fine but what I want is mentioned in previous comment.

Try this.

figure
h1 = bar(X, 0.25);
cmap1 = cool(3);
h1(1).FaceColor = cmap1(1,:);
h1(2).FaceColor = cmap1(2,:);
h1(3).FaceColor = cmap1(3,:);
hold on
h2 = bar(Y, 1);
cmap2 = winter(3);
h2(1).FaceColor = cmap2(1,:);
h2(2).FaceColor = cmap2(2,:);
h2(3).FaceColor = cmap2(3,:);
legend('Series1','Series2', 'Series3','Series4','Series5', 'Series6');

Thank you @KL, This solves my problem.
