3. Russet [?r?s?t]
紅棕色

Being a reddish brown, russet is a popular fall color. Its name is a borrowing of an Anglo-French adjective, meaning "reddish" or "reddish-brown," that came to designate a coarse, homespun cloth used to make garments. English borrowed the French term for the cloth in the 13th century before using it in its color sense.
Russet指紅棕色，是一種常見的秋天代表色。這個單詞是諾曼時代英國所用法語中的一個形容詞，原意為“略帶紅色的”或“略帶紅棕色的”，指代一種粗糙的土布衣料。13世紀時，人們將這個法語單詞引入英語中，之后取其色彩含義使用。

Association of the word with rural living led to its use as an adjective meaning "rustic," "homely," and "simple."
因為russet和鄉村生活有關，因此也可以做形容詞表示“樸素的”、“家常的”、“簡單的”意思。

4. Amber [??mb??]
琥珀色

Amber can describe the dark orange-yellow color of a floating leaf or a substance found floating in the sea. It is derived from Arabic, anbar, which refers to ambergris, a waxy secretion of the sperm whale that is used as a spice and in perfumery. In English, amber was originally used as the name for this substance, with the name ambergris developing later in French from ambre and gris ("gray") to differentiate it from the fossilized tree resin type of amber, which is also found around the shore (of the Baltic Sea, largely).
Amber（琥珀色）可以用來形容暗橘色的浮葉，或者海上的漂浮物。這個單詞源于阿拉伯語中的anbar，指的是一種制作香料和香水的原材料——龍涎香（抹香鯨的蠟狀分泌物）。Amber在英語中原本是龍涎香的名字。為了區分龍涎香和化石樹脂型琥珀（大部分化石樹脂型琥珀發現于波羅的海海岸），后來法語中出現了ambergris（龍涎香）的說法，這個單詞由ambre和gris（同gray，灰）組成。

Species of insects and plants have been found as fossils in this yellowish to brownish amber, and deeply colored, translucent pieces are used in making jewelry and ornamental objects. It is from the color of this resin that amber has come to refer to a dark orange yellow.
這種黃棕色的琥珀中間包裹著昆蟲和植物化石，而顏色濃且透亮的琥珀可以制作珠寶和裝飾品。人們因為琥珀的顏色而用amber來指代暗橘黃色。
