[Gnuplot-info] color blindness and gnuplot default colors

[Micha W. <mw...@gm...>]

Hi there,

gnuplot default colors seem to be

1 red
2 green
3 blue
4 magenta
5 cyan
...

I think it would be helpful for people with color blindness to change 
that order into

1 red
2 blue
3 magenta
4 cyan
5 green

This makes the clas of red and green less likely.

A workaround is using linetype in the plot command as in

plot [][-1:1] sin(x), cos(x) lt 3, tan(x) lt 4, x lt 5, x**2 lt 2, x**3

or defining line styles

set style line 2 lc 3
set style line 3 lc 4
set style line 4 lc 5
set style line 5 lc 2
set style increment user
plot [][-1:1] sin(x), cos(x), tan(x), x, x**2, x**3

But this is lots of work on a day by day basis and I see no argument 
against change gnuplots default, at least moving green down in the color 
list.

Best regards, Micha
