no one favorite --- many i really like, many favorites you could say, often depending on the exact shade (in other words, not "green" on a whole, but some kinds of green). favorites that come to mind at the moment: brown (rich chocolate-y brown), bright blood/cherry red, deep indigo (true blue/purple mix, like a late evening sky or irises), amber/caramel/golden brown (like amber or the hair color), the color of red mahogany wood, turquoise, ........ actually, this is a long list. interesting question - what kind of colorblind are you? in other words, how do you perceive colors?
