How can I plot histograme of a vector with four values independant?
v=[1; 2;0;1]

If those values describe the bar height, you could use bar(___,width) and specify the width of the bars as 1 to resemble a histogram.
v=[1; 2;0;1];
bar(v,1) % figure shown below
Alternatively, you can use histogram('BinEdges',edges,'BinCounts',counts) which specifies the bin edges.
histogram('BinEdges',.5 : 1 : 4.5,'BinCounts',v)

You'll need to be more specific.

each bar of the histogramme with a different color

If you're using the bar() approach,
b = bar(v,1);
b.FaceColor = 'flat';
b.CData = [1 0 0; 0 1 0; 0 0 1; 1 1 0]; % set color of each bar
If you're using the histogram() approach, you'll need to loop through each value of v and plot each bar separately (this is not recommended).
