looks like you will have to modify the code, and put the appropriate
color keyword into the plot command:
F'rinstance

plots,[x0,x1,x1-(ct*dx/xd-st*dy/yd)*xd, $
x1,x1-(ct*dx/xd+st*dy/yd)*xd], $
[y0,y1,y1-(ct*dy/yd+st*dx/xd)*yd, $
y1,y1-(ct*dy/yd-st*dx/xd)*yd], $
clip=clip,noclip=noclip,_EXTRA=extra,color=colorvalue[i]

where you have created the appropriate colorvalue vector.

Cheers,
bob
