[5] At the debut showcase, Kang stated the album's title was inspired from the second track "Color" since he wanted to show his diverse sides.

Following his legal dispute with his former agency and subsequent six-month hiatus from the entertainment industry, Kang revealed that the entire album was prepared within just two weeks.

In an interview with Bandwagon Asia explaining her creative process, she revealed that both her and Konnect Entertainment were in agreement to emphasize Kang's presence as a solo artist and "wanted the album to look like a special edition from a fashion magazine".

[11] Following that, Kang kicked off the international leg of his fan meeting tour with stops in Singapore, Bangkok, Taipei, Kuala Lumpur, and Manila.

[16] As of July 31, the third day since the EP's physical release, Color on Me sold over 400,000 copies, also breaking the record for the highest first-week sales for a soloist in the history of Hanteo Chart.

[19] Later that year, Sony Music Entertainment announced its biggest global sellers for its second fiscal quarter of 2019 with Kang's Color on Me placing fifth.
