|Yui singles chronology|
"Namidairo" is the eleventh single by Japanese pop singer-songwriter Yui. The single was released on February 27, 2008. The title song is a tie-up for the TV drama, 4 Shimai Tantei Dan.
Background and writing
Yui began writing the lyrics soon after her concert at Nippon Budokan on November 19, 2007. In an interview with Excite on February 2008, she revealed the melody of the chorus was actually from her second single, Tomorrow's Way, but she only wrote it halfway. She completed the song by including new A and B melodies, and the lyrics.
Although told to write the theme song for the drama, she had the consent to write as she wished. Consequently, Yui tried not to put all the emphasis on "love", as was the main theme of 4 Shimai Tantei Dan, but on relationships between individuals as well.
The title, "Namidairo" (ナミダイロ), in Japanese literally means color of tears. Yui used this phrase to mean the crying of the heart, but she also said listeners will likely decide on their own meaning for the word. 
The music video begins with Yui playing guitar in a room. From thereon, the video cuts to Yui walking down a street or riding a bus alone, sitting in a telephone booth, or back to the room. The video ends with Yui in the telephone booth looking outward at floating lines of light.
