The British spelling of Technicolor. In British English you meet it mostly in one fixed phrase: "in glorious technicolour". It means you see something in full, bright, unmissable colour on a screen — and the tone is usually playful or slightly exaggerated. "There it was on the six o'clock news, in glorious technicolour." That phrase has drifted beyond colour. People now use it for anything seen or described in embarrassing, uncomfortable detail — "he told us about his divorce in glorious technicolour". Nothing colourful is involved; "technicolour" is doing the work of "far more vividly than I wanted". You will hear a little dry humour in it almost every time. As a plain adjective it works like the American form: "technicolour dreams", "a technicolour display", meaning strikingly, unnaturally bright.

（英式拼法）鮮豔的、彩色的；片語 in glorious technicolour 意思是「一清二楚、活生生地呈現在眼前」，常帶點調侃，接近中文說的「看得一清二楚」「鉅細靡遺」。
