Different colors in Histogram (MATLAB)

Dear;

I have created this simple program to plot the histogram of these values:

Iter=[30 55 64 130 186 432];
SNR=[9 8 8 9.3 6 6.7];
stem (Iter,SNR,'linewidth',2);
axis([0 450 0 10]);
xlabel('Number of iterations');
ylabel('SNR(dB)');

Can you help me to change the color of each bar please.

Also I want to place a text atop each bar. How can I do that ?

Iter=[30 55 64 130 186 432];
SNR=[9 8 8 9.3 6 6.7];
color = {'r','b','g','y','m','k'} ; 
figure
hold on
for i = 1:length(Iter)
    stem (Iter(i),SNR(i),'linewidth',2,'color',color{i});
end
axis([0 450 0 10]);
xlabel('Number of iterations');
ylabel('SNR(dB)');
