My question is how can I change the bar colors when using

HTML Code:
coefplot
I tried this:
HTML Code:
  bar(1,bcolor(navy)) bar(2, bcolor(maroon))
option bar() not allowed r(198);

HTML Code:
coefplot fcn1 fcn5, format(%9.0f) ///
title("(a) Overall Perception of China", size(medium)) ///
color(navy) lcolor(black) lpattern(solid) byopts(cols(1)) ///
ciopts(recast(rcap)) citop citype(logit) ///    
recast(bar) rescale(80) vertical  ///
ytitle ("") ///
graphregion(color()) yscale(r(0 50)) ylabel(0(10)50) ///
addplot(scatter @b @at, ms(i) mlabel(@b) mlabpos(2) mlabcolor(black)) ///    
xlabel(1 "Favourable" 2 "Neutral" 3 "Unfavourable") ///
ylabel(, labcol(black)) barwidth(.3) legend(label(1 "Remainers") label(3 "Leavers") ring(0) position(2) bmargin(large))
