changing color for each bar plot

How can i can change color for each color in bar plot . I am saving all this values in an percBar and doing a bar plot how can I change the individual color for an bar like for first 3 it should be red , next 3 blue and last green .. I tried but it is taking the last color only i.e green .... How can I add set of 3 color to the plot ......Thank you in advance....I am using 2016B matlab version

t= [ 200 500 1000]

%% O2 Pollutant

% t=[572,922,2000]; %%% Time to measure the Pollutant Scores

EO_10=round(FlowMng_v401_1_O2_sim_mass_cum(t(1)));

EO_45=round(FlowMng_v401_1_O2_sim_mass_cum(t(2)));

EO_200=round(FlowMng_v401_1_O2_sim_mass_cum(t(3)));

%%% score at times After TWC1 Conditions

C1_10=round(BK401d1_1_O2_sim_mass_cum(t(1)));

C1_45=round(BK401d1_1_O2_sim_mass_cum(t(2)));

C1_200=round(BK401d1_1_O2_sim_mass_cum(t(3)));

%%% score at times After TWC2 Conditions

C2_10=round(BK401d1_2_O2_sim_mass_cum(t(1)));

C2_45=round(BK401d1_2_O2_sim_mass_cum(t(2)));

C2_200=round(BK401d1_2_O2_sim_mass_cum(t(3)));

%%% Plottting

hold on

percBar= [EO_10,C1_10,C2_10,EO_45,C1_45,C2_45,EO_200,C1_200,C2_200];

%%% plotting with different colours

col=[ 'r' 'r' 'r' 'b' 'b' 'b' 'g' 'g' 'g'] % setting color

xtics=[1:1:9]

h= bar(xtics,percBar)

for i= 1:3:9

set(h,'FaceColor',col(i)) % adding facecolor to the bar plot

end

xticlab={'EO-10' 'C1-10' 'C2-10' 'EO-45 ' 'C1-45' 'C2-45' 'EO-200' 'C1-200' 'C2-200'};

set(gca,'XTick',xtics,'XTickLabel',xticlab,'Fontsize',8)

text(xtics,percBar,num2str(percBar'),'vert','bottom','horiz','center');

See the Control Individual Bar Color example on the bar documentation page.

That the issue this b.CData(2,:) = [.5 0 .5]; is not working in Matlab 2016 b ....

Here's an example of my interpretation of how to do this.

percBar= {'EO_10','C1_10','C2_10','EO_45','C1_45','C2_45','EO_200','C1_200','C2_200'};
x = 1:9;
y = [75 91 105 123.5 131 150 179 203 226];
c = jet(length(y));

for a = 1:length(y)
    b=bar(x(a),y(a),'FaceColor',c(a,:),'barwidth',0.9);
    hold on
end
hold off
xticks(x)
xticklabels(percBar)
set(gca,'TickLabelInterpreter','none')
