This is fixed in Scilab 6.

You may use this:

xf  =  [1   -1  -1  1   1   0.5  0.5  -0.5  -0.5   0.5]';  
yf  =  [-1  -1   1  1  -1  -0.5  0.5   0.5  -0.5  -0.5]';  
zf  =  zeros(yf);
red  =  color("red");
plot3d(xf,  yf,  list(zf,  red))//Facet
set(gce(),  "foreground",  red,  "hiddencolor",  red);
