Plotting colored points with PLOTS [message #553]

I am trying to use PLOTS to plot points so that the color of the point
depends upon a third parameter (tag). Can anyone tell me why this works:

FOR i = 0, n-1 DO BEGIN
PLOTS, x(i), y(i), PSYM=3, COLOR=tag(i)
ENDFOR

but this doesn't?

PLOTS, x, y, PSYM=3, COLOR=tag

The documentation says that color can be a vector for PLOTS. I am running
IDL 2.3.2 under AIX 3.2.

Thanks, Ken Bowman
