Changing each bar in a plot a specific color

I have a for Loop that with each loop create a plot and fit a linear regression to that plot. At the end i want to create a subplot as a bar diagramm that compares the gradient of the lin regression. With the following code it creates the bar diagram. My problem is that with each loop the plots have a specific color. The Bar diagram should fit that color so that the graph1 with the linear regression 1 and the bar1 all have the same color. In my loop it works to just reference to my c but with the bar diagram it doesnt work.
number = numel(data);
for i = 1:number
c = {'b','r','g','y','k'};
c2 = {[0.4;0.5;0.7],[0.8,0.4,0.5],[0.2,0.3,0,3],[1,0.9,0.7],[0.5,0.6,0.7]};
p{i} = polyfit(x_relevant{i}, y_relevant{i},1);
fit{i} = polyval(p{i},x_relevant{i})
p3 = plot(x_relevant{i},fit{i},'color',c{i},'LineWidth',3)
end
coefs = cell2mat(p(:));
subplot(4,1,4)
b = bar(coefs(:,1));
b.FaceColor = 'flat';
b.CData = c{i};
--->
Error setting property 'CData' of class 'Bar':
Value must be a scalar, vector or array of numeric type
if i change the last line to
b.CData = c2{i};
it semi works. The color changes but all bars have the same color(the one for c2{2}) which makes sense bc my i is 2 after the for loop but even if i put the bar plot inside my for loop it just is 2

%true
hold on
b1 = bar(coefs(:,1));
hold on
b2 = bar(coefs(:,2));
set(b1,'FaceColor',c{1});
set(b2,'FaceColor',c{2});
Try hold on btw bar plots
