Sky-blue is a bright, light blue — the colour people picture when they look up on a clear day and there are no clouds. You use it like any other colour word: a sky-blue shirt, sky-blue walls, sky-blue paint.

Sky-blue is是 a bright, light blue一種明亮的淺藍—— people就是人們 on a clear day在晴天 and there are no clouds萬里無雲的時候 when they look up抬頭看 picture心裡浮現的 the colour那種顏色。 You你 use it用它 like any other colour word就像用其他任何顏色的字： a sky-blue shirt天藍色的襯衫、 sky-blue walls天藍色的牆、 sky-blue paint天藍色的油漆。

You will also see it written as two words, sky blue; both are fine. The hyphen just glues the two ideas into one colour name.

You你 also也 will see it written會看到它寫成 as two words兩個字， sky blue； both兩種 are fine都可以。 The hyphen連字號 just只是 the two ideas把兩個概念 glues黏 into one colour name成一個顏色名。

Though actually the real sky is not always this colour — dawn can be pink, and a rainy day is grey — so the word points to a kind of ideal, sunny blue, not every sky you will ever see. It is an ordinary, everyday word, not fancy and not technical.

Though actually不過其實 the real sky真正的天空 is not always不一定總是 this colour這個顏色—— dawn清晨 can be pink可以是粉紅的， a rainy day雨天 is grey是灰的—— so所以 the word這個字 points to指的是 a kind of ideal, sunny blue一種理想中、有太陽的藍， not不是 every sky you will ever see你這輩子會看到的每一片天空。 It它 is an ordinary, everyday word是個普通的日常用字， not fancy不花俏 and也 not technical不是術語。

As a noun it can also mean the colour itself: she painted the door a lovely sky-blue.

As a noun當名詞用時 it它 also也 can mean可以指 the colour itself這個顏色本身： she painted the door a lovely sky-blue 她把門漆成很好看的天藍色。
