Color Combination as a Trademark.

Trade dress, a “symbol” or “device” by which the goods of a manufacturer may be distinguished from the goods of others, is registrable as a trademark if its function is to identify the source of the goods. Trade dress may be the total image of a product and may include features such as size, shape, color or color combinations, texture, graphics, or even particular sales techniques.

產品包裝上的色彩組合和設計可以作為商標。商業外觀是一種“符號”或“裝置”，可以用來將製造商的商品與其他商品區分開來，如果其功能是識別商品的來源，則可以作為商標註冊。 商業外觀可能是產品的整體形象，可能包括尺寸、形狀、顏色或顏色組合、質地、圖形甚至特定的銷售技巧等特徵。
