gnuplot, postscript: no coloring via linestyle

In the below code, the appearance of the curve plotted takes into account linetype and linewidth but it completely ignores linecolor.

set style line 1 linetype 1 linewidth 10 linecolor rgb "blue" 
plot \
myfile using 1:2 with lines linestyle 1

I have tried to change the order of these items, as well as different ways of specifying color, eg. "#0000FF" instead of "blue".

How can I change this to have the curve take on the color specified via linestyle 1?

This is gnuplot 5.4 on Mac OS / Big Sur, tried with "Terminal" and "iterm2".

IMPORTANT UPDATE

I'm using set term postscript eps. When i change this to set term pngcairo everything is ok.

So my updated question is: How to make this work also with set term postscript eps?

Apparently, the default setting for the postscript terminal is monochrome and you have to explicitely set color. I remember having seen similar questions in the past. I don't know why default is monochrome, maybe historical reasons? So, it seems to be a recurring "pitfall", since users nowadays think everything is in color per default ;-).

set term postscript eps color

That's what I get (on a "fresh" console) if I type set term postscript eps. Apparently, text is in color per default (i.e. labels and arrows), but the rest seems to be monochrome.

Options are 'eps enhanced defaultplex \
   leveldefault monochrome colortext \
   dashlength 1.0 linewidth 1.0 pointscale 1.0 butt noclip \
   nobackground \
   palfuncparam 2000,0.003 \
   "Helvetica" 14  fontscale 1.0 '

set term epslatex

...and it works! (since i wanted "eps", and got "eps").

Incidentially (although it produces "png" instead of "eps") set term pngcairo and possible many more "term"s also work.

Strange thing is that I didn't get any warning when plotting with set term postscript eps that gnuplot was not able to apply the linestyle coloring with that terminal mode.
