teal and cerulean

今日はThe Art of ChoosingのI, Robot?の章に出てきた色を示す単語を覚えます。
Yet even in this riot of color and style, there are patterns. Bold primary colors seem quite popular, and you begin to notice many cool colors as well: green shirts, teal blouses, cerulean and azure dresses and skirts.
著者のSheena Iyangarさんはインド出身で盲目の女性ですが、インターネットの動画を参照したり、上記の個所のようにビジュアルの判断を必要とする内容が結構多く、目が見えなくてどうしてこの様な文が書けるのか不思議です。それはともかく私としては上に出てきた "teal" と "cerulean" の色を覚えたい。まず "teal" は：
・Oxford English Dictionary: A dark greenish-blue color.: I would say the best dress this month has got to be Naomi Watts wearing that Roly Mare dress with the square neckline, form-fitting, and a beautiful sort of teal blue.
・Wiktionary: A dark, somewhat bluish-green colour; a dark cyan.
次に "cerulean" は：
・Oxford English Dictionary: Deep blue in color like a clear sky: cerulean waters and golden sands
・Wikipedia: Cerulean, also spelled caerulean, is a color term that may be applied to certain colors with the hue ranging roughly between blue and cyan, overlapping with both. It also largely overlaps with azure and sky blue, although cerulean is dimmer.
"azure" との区別が難しい。まあ感覚の問題でしょうね。 "cerulean" は発音にも注意です。私は大抵の場合発音はONLINE Merriam Webster Dictionary で確認しています。
