If you were asked to pick a color associated with Tokyo, what color would that be? I think the first colors that come to mind for most people would be red and black but the city offers a veritable rainbow, or niji, of colors to her visitors. Let’s explore the colors of Tokyo…
Aka (Red) is the color of the circle representing the sun on the Hinomaru, the flag of Japan, and is considered good luck. The Kaminarimon Gate in Asakusa and many of the shrines around Tokyo are painted in this deep crimson color.
Kiiro (Yellow) is the color of the Ginko biloba leaves in the fall. Better know for their green color, the Ginko biloba leaf is one of the symbols of the Tokyo Metropolitan Government.
Midori (Green) can be found in the parks and gardens that are pockets of natural beauty amidst the modern architecture and noise of this bustling city.
Sakurairo (Pale Pink) is the color of spring in Tokyo and the color of the cherry blossoms that bloom each year.
There are so many other colors that Tokyo has to offer, there is the blue and white of the traditional pottery and fabrics, the white and silver that is ever present on the modern architectural wonders that grace the Tokyo skyline, and the black sumi ink that artists use to create renderings of the kanji and Japanese poetry that are gorgeous in their simplicity.
Lastly, covering the whole spectrum of color is the aptly named Rainbow Bridge in the Odaiba area of Tokyo. 
Come explore the rainbow of colors that Tokyo has to offer, you won’t be disappointed!

东京——色之虹(虹之都)
如果让你选一个颜色来形容东京,你会选哪一个呢?我想大部分人脑海中首先涌现的颜色是红色与黑色,但是这座城市向游客展现了真正的彩虹,或者说niji(虹)。让我们开始东京之色的探索之旅吧。
Aka (红色) 日本国旗上代表太阳的圆圈的颜色,日本人认为它代表了好运。浅草的雷门和东京周边的许多神社被漆成这种深绯红色。

Kiiro (黄色)是深秋银杏叶的颜色 . 银杏叶的绿色更为著名, 它是东京都政府的标志之一。
Midori (绿色) ,我们可以在公园里发现它。那里,是夹杂在现代城市和这个繁华城市的噪音下零星的自然美景。
Sakurairo (淡粉红色) 是东京春天的颜色,也是每年绽放的樱花之色。
东京还展现了许多其他颜色,是传统陶器和织物上的蓝色与白色,也是为东京天空增色的现代建筑奇迹上的白色与银色 ,也是艺术家用来创造汉字体系译文和因简单而华丽的日本古诗所用的墨汁里的黑色。最后,覆盖了整个颜色光谱的是在东京台场恰好叫做彩虹桥的地方。

来探索东京所展现的色之虹吧,你不会失望的!
