am i the only one here who almost can't tell the yellow and red ones apart?... why can't one be so completely different in color, instead of so close, that old eyes like mine won't confuse the two? like, have one be blue, or green? pretty please! ps: why do some last words on the line get duped in the next line when posted?... i just checked and i have only one 'completely' in my post box, but it comes out duped in the thread!
