How to draw a histogram with different bin colors based on value?

Suppose I have a vector of [-2, 3, 1, 2, -1, -2], and I want to create a histogram that with red bins when the element of vector>0 and blue bins when <0.

How could I do that?

Thank you!

v = [-2, 3, 1, 2, -1, -2] ;
x = 1:length(v) ; 
figure
hold on
bar(x(v<0),v(v<0),'r')
bar(x(v>0),v(v>0),'b')
