No, no, Nora, the Ferreter got it right this time. Blue becomes green when
you add even the slightest yellow. And yellow becomes green when you add
the slightest amount of blue. Light dawns on a difficult problem. How easy
it all is. And how very green!

I woke up this morning and walked outside, admiring the green garden under
a sky as green as sapphire, in which the sun shone brightly and greenly. A
sun-tanned girl walked by with hair as green as straw, matching her eyes
which were green like the purest water. She was a devil with the green
dress on!

if we apply the same criteria to species, then taxonomy will be greatly
simplified. Thanks for the inspiration, ferreter!
