Assigning colors to histogram bars

[amateur_expert]

I want to overlay 2 histograms (age in men and women) for 2 groups (rural vs. urban population). 

My code below works but the histogram bars are in reversed colors - in 1 figure, women are red, and in the other one, blue. How can I assign the same colors in both figures?

proc sgplot data = data;
histogram AGE / group = SEX;
by URBAN;
RUN;

Try sorting

proc sort data=data;
    by urban sex;
run;
