提起天空的顏色，大家可能都會下意識地想起淡淡的粉藍。事實上，大自然是最不受限制的調色盤，天空的顏色隨著時間、季節更迭，千變萬化不下於雲朵的形狀。雖然如此，記錄天空的顏色並非不可能的任務。早在 1789 年，瑞士物理學家 Horace-Bénédict de Saussure 和德國博物學家 Alexander von Humboldt 便共同發明了一個神奇的儀器，用來測量天空中各式各樣的「藍」：http://www.biosmonthly.com/contactd.php?id=4748
A cyanometer (from cyan and -meter) is an instrument for measuring 'blueness', specifically the colour intensity of blue sky. It is attributed to Horace-Bénédict de Saussure and Alexander von Humboldt. It consists of squares of paper dyed in graduated shades of blue and arranged in a color circle or square that can be held up and compared to the color of the sky.
De Saussure is credited with inventing the cyanometer in 1789.[1] De Saussure's cyanometer had 53 sections, ranging from white to varying shades of blue (dyed with Prussian blue) and then to black,[2] arranged in a circle; he used the device to measure the color of the sky at Geneva, Chamonix and Mont Blanc.[3] De Saussure concluded, correctly, that the color of the sky was dependent on the amount of suspended particles in the atmosphere.
Humboldt was also an eager user of the cyanometer on his voyages and explorations in South America.[4]
The blueness of the atmosphere indicates transparency and the amount of water vapour.

氰的化學性質與鹵素很相似，是擬鹵素（或類鹵素）的一種。氰氣會被還原為毒性極強的氰化物。氰在高溫下與氫氣反應生成氰化氫。與氫氧化鉀反應生成氰化鉀和氰酸鉀。氰加熱至400°C以上聚合成不溶性的白色固體(CN)x。
