Hello,

I'm plotting data from files: each files produces a colored curve.
Gnuplot default behaviour makes each curve beeing colored with different color which is what I want.

But as you may see in the following png file (even if my final result will be a pdf file), curve colored in yellow isn't well visible.

How can I avoid Gnuplot to use yellow color (#ffff00) for plotting curves?

I didn't use any special palette and let Gnuplot do the job with "plot file1.dat with steps title "number", file2.dat with steps...

You simply change the default colour of lt 5

	set linetype 5 lc rgb "dark-orange"

Thank for your answer Karl.
But this postpone the problem until later.
As we can see with plotting here 27 data files, yellow color appears later several times:

Michael, your solution limits colors number but anyway it's smart.

How can I avoid every "yellow" occurences?

set term pngcairo
set out 'no_yellow.png'
set for [i=6:300:9] linetype i lc rgb "dark-orange"
unset key
plot [][-1:101] for [i=1:100] i w l

Super!
Merci for line 3 ingenious loop.
I missed 9 step period.

How do I can tag post as "solved"?

You can define your own colors:
mycolors='0xFF0000 0x00FFFF 0x00FF00 0x0000FF'
plot [][-10:10] for [i=1:4] i w l lc rgbcolor word(mycolors,i)
