According to the booklet contained in Splatune, it was revealed that City of Color was the Squid Sisters' debut song.

Lyrics
The booklet included with Splatune gives the official lyrics for City of Color. The lyrics are nonsensical; the Japanese hiragana simply gives the pronunciation.

Maritime Memory
Maritime Memory is a much slower cover of City of Color with a nearly completely different instrumental.

Inkopolis News (Splatfest)
This is simply the instrumental version of City of Color without the Squid Sisters singing, which also includes the Inkopolis News saying heard in the original Inkopolis News song. It was played immediately after the player has pressed and  on the start screen during a Splatfest and played during Inkopolis News, replacing the regular Inkopolis News song. After the news segment ended, the vocals were added, transitioning it to the regular version.

Splatfest theme announcement jingle
This is a very shortened version of the song's intro with a lower pitch. It was played during Inkopolis News when the Splatfest theme was announced.

Splatfest final result jingle
Like the announcement jingle, this is a very shortened version of the intro, but with a more twinkly sound. This was played during Inkopolis News once the winner of the Splatfest was announced.

City of Color (Live)
During live Squid Sisters concerts, an extended version of City of Color is used. Although each performance is different due to the live bands, they retain the same strong structure. There is a new guitar solo not found in the original, along with a slightly altered instrumental after the solo. Then it has a new outro, featuring another guitar solo before the song ends. Two recordings of this version from Shiokalive 2016 and Shiokalive at Chokaigi 2016 (labelled as 1st and 2nd live versions respectively) can be found in Splatoon Live in Makuhari.

City of Color (Shy-Ho-Shy Demo)
An early version of City of Color was released with Splatoon Live in Makuhari, featuring a much simpler instrumental than the final product and different vocals. Shy-Ho-Shy, the Squid Sisters' producer, was first mentioned in the booklet for Splatune as the committee member that originally discovered their talent. The vocals heard in the song are not from the Squid Sisters, but rather Shy-Ho-Shy herself. The demo was produced as a reference for the Squid Sisters during the making of the song and might have been recorded while they were practicing it.

Octo Eight-Step
Octo Eight-Step by Turquoise October samples Callie's vocals from City of Color and reverses them.

Spicy Calamari Inkantation
The melody of City of Color's chorus can be heard after the end of the chorus of Spicy Calamari Inkantation during the small instrumental break. After the instrumental break, there are a few vocals before a new short instrumental break which is also from City of Color.

Trivia

 * Due to the end of Splatfests in Splatoon, it is now impossible to listen to City of Color in Squid Beatz if the player has not participated in any Splatfests. Although one can still listen to the song through the amiibo performances, this still does not unlock it in Squid Beatz.

Etymology
City of Color is named after the appearance that Inkopolis Plaza took during Splatfests, with it being lit up by neon signs, bright lights, and fireworks.
