black, gray
and white could be good to mean the tripolar logic... though, why just
tripolar? An other shades pattern could mean
cai-sai-.-cu'i-ru'i-nai,...but there can be caisaicu'iru'inai :-)
That's a great idea!! And yeah, even though you can go all crazy with
it, tripolar logic is something that sets Lojban apart from most other
languages--the third pole is the truly good idea; all other poles are
just more of the same. Also, flags shouldn't have more than three
colors.
A neat, simple, meaningful, conformist, modern-looking flag might just
be three vertical bars: black, grey, white.
