How do I modify colors in a stacked bar graph?

I have a stacked bar graph and would like to color the stacks according to their position in the vector, but each value doesn't always get printed.
m1{1,1}=0.0193; %only a single value in this position
m1{2,1} = [-0.0155 0.0117 -0.0037 -0.0856 0.0180];
m1{1,2} = [-0.0340 -0.02889 -0.0359 -0.1049 -0.0255];
m1{2,2} = [-8.5343e-04 0.0213 0.0129 0 0.0243];
%There are 5 values in each cell. I am stacking these values but I don't want them crossing zero so I plot + and - separately. I want to plot each cell as series in the bar plot (so they should be touching) and then do this for 3 months on the same graph.
cl_colors={'r','y','g','b','c'};
f1p=find(m1{2,1}(m1{2,1}>=0));
f2p=find(m1{2,2}(m1{2,2}>=0));
f1m=find(m1{2,1}(m1{2,1}<0));
f2m=find(m1{2,2}(m1{2,2}<0));
% I was hoping this could be used to define the colors of my stacks. For example, if bar1 plots the numbers from positions 1,3,4 then I want the colors of those stacks to be r,g,b. It's important that the colors always associate with the position in the vector.
bar1=bar([[m1{2,1}(m1{2,1}>=0) zeros(length(m1{2,1}(m1{2,1}<0)),1)'];...
[m1{2,2}(m1{2,2}>=0) zeros(length(m1{2,2}(m1{2,2}<0)),1)']],'stack','BarWidth',1,'FaceColor',{[cl_colors(f1p) 'w' 'w' 'w'];[cl_colors(f2p) 'w' }));
hold on
bar2=bar(get(bar1,'XTick'),[[m1{2,1}(m1{2,1}<0) zeros(length(m1{2,1}(m1{2,1}>=0)),1)'];...
[m1{2,2}(m1{2,2}<0) zeros(length(m1{2,2}(m1{2,2}>=0)),1)']],'stack','BarWidth',1,'FaceColor',{[cl_colors(f1m) 'w' 'w' ];[cl_colors(f2m) 'w' 'w' 'w' 'w']}));
% In the above statement (which doesn't work for assigning facecolor), using 'w' based on manual inspection is less than ideal so I am hoping someone has a suggestion for this. The final product should also have m1{1,1} as a single black bar. Based on other posts, I tried to get(bar1,'Children') and then changing the facecolor or cdata but to no avail.
Let's say that's the data for Mar, How do I then plot the data for Apr in the same configuration spaced away from the Mar series? Thanks!
