青 in Chinese / Japanese...

青 is nature's color and can refer to forest green, greenish-blue, or the darkest of greens.

青 and color represent nature, youth, and young people.

In the same way, we refer to green bananas and the rookie being green, the same is true in Chinese and Japanese, where, in a certain context, this can mean immature, unripe, or young.

In Japan, this can also be a female given name “Haru.” It can also be used as a given name (for either sex) in China.

青天 means clear sky and/or blue sky in Chinese and Japanese Kanji.

Sometimes this term is used in Chinese to refer to an upright and honorable official or politician (a very rare thing).

In Japanese, this can also be the name Harutaka.

青色 is a Chinese word that is used for the color cyan.

This can also refer to a blue-green color.

In Japanese, this is an alternate way to refer to a blue color.

青玉 is a Japanese word that means sapphire or jacinth.

Note: This also makes sense in Chinese, but will be read as "blue jade", rather than being understood to be sapphire (藍寶石 is sapphire in Chinese).

This is the Japanese place name, Seikan.

This place particularly famous for the engineering feat of the submarine Seikan Tunnel.

青龍 is a scholarly title for “Blue Dragon” or “Azure Dragon.”

You'll find this title used in ancient Chinese literature and astronomy. This dragon has dominion over the eastern sky or eastern heavens. The Azure Dragon is also noted for representing the spring season. Also seen as an auspicious omen.

Emperor Huizong of the Song Dynasty canonized the five colored dragons as “kings.” The Azure Dragon represents the most compassionate of kings.

In Japanese, this title is known with the same meaning but can also be a given name, Seiryuu or Seiryu.

Note, the first character can be written as OR . Same character, just two ways to write it.

爐火純青 means “[The] furnace fire [has become] pure green.

This is an allusion to Daoist alchemy. figuratively, this speaks of an art or technique brought to the point of perfection.

青梅竹馬 means “green plums and hobby-horse.”

Figuratively, it means “innocent children's games,” “childhood sweethearts,” or “a couple who grew up as childhood friends.”

This phrase may sound a little strange as it's a kind of Chinese proverb or idiom. It makes much more sense in Chinese than in English.
