For trees my favourite color is green, while for fire engines it is red.
This is something you don't have to back up with some arguments, as a non-green tree (at least from spring to fall) doesn't look that healthy and who has ever heard of a yellow fire engine?
Well, actually, there was an experiment out here in the wild woolly west of California where, for a year or so, new (?) fire engines were, in fact, painted yellow. It was a kind of dull yellow, not as bright as a school bus, but my family always used to joke about the school buses with sirens. I haven't seen any in a while, although there are some white ones, too.
Aside from the obvious deficiency, yellow has this unusual quality of being invisible under certain types of low power street lamps....
I guess some people just don't see red that well?
