Re: What happens when passing `fg=...,fg=...' to region_highlight, how is this defined?

[Sebastian Gniazdowski <sgniazdowski@xxxxxxxxx>]

Just thought that maybe Zsh just sums up the color indices :)
Immediate confirmation is not there, 169...171 (114+55, etc.) goes
from reddish to a purple.

However looking little up, there is 157, 158, 159 that apparently
matches the colors of $PATH in the attached image.

I use this to see the palette:
 ▲ ~ which palette
palette () {
    for n in {000..255}
    do
        colors+=("%F{$n}$n%f")
    done
    print -cP $colors
}
