Ðonald, I like your first idea (the grey lines) because on the second
it is hard to see the difference, I think... Hard to spot it because
there are already several colors but on the first it's black all the
time, so that it's easy to see the lines.
My opinion.
Spug
PS. Jim, on your HS example, you wrote Spud instead of Spug - and
it's the second time you do it :) It doesn't matter, just telling...
