It's been several months since one of my favourite anime from the Summer 2016 season, "Kono Bijutsu-bu ni wa Mondai ga aru!" (この美術部には問題がある!), finished its run, and being a fan of the comedic slice-of-life sub-genre, the show managed to fulfill a promise that any televised project wants to achieve...leave the audience wanting more. I've read that the original manga is still plowing ahead but I don't know whether there will be a second season. However, that ending scene in the final episode was good enough for me.
Of course with this blog, I've brought in the anime for the purpose of introducing anison earworms and near-earworms, and what also helped "Konobi" was the really catchy themes of Nana Mizuki's（水樹奈々）"STARTING NOW!" and Sumire Uesaka's（上坂すみれ）"Koi suru Zukei (cubic futurismo)"（恋する図形）. And of course, I already wrote about those two tunes as the series was wrapping up.
However, I neglected to talk about a cute little tune adorably sung by Ari Ozawa's（小澤亜李）main character of Mizuki Usami（宇佐美みずき）during a brief montage scene in the penultimate episode which involved prepping for the annual Culture Day festival at the school. I later found out that the song was titled "Kokoro Palette" (Heart Palette).
Then "Kokoro Palette" came out in its full rousing glory as the ending theme for that final episode with the four main female seiyuu, Ozawa, Mizuki, Uesaka and Nao Toyama（東山奈央）bringing the group effort. I was finally able to get my own copy of "Konobi" and enjoyed my second round; listening to the song once more made me realize that this was a pleasant and worthy song to talk about.
But the final trigger was when I was reading the "TV Tropes" entry on the show and I discovered this kernel of knowledge in the YMMV section. Apparently, the song wasn't a product of the anime and was actually a campaign song for the manga by Imigimuru (いみぎむる) a number of years before. I couldn't be sure of the actual year that "Kokoro Palette" was recorded but considering that the original manga came out in 2012 and the YouTube video above was uploaded in 2013, I think 2013 is a fairly safe bet.
The original recording artist was a Vocaloid by the name of GUMI with "Kokoro Palette" written and composed by musician 40mP. It was a hard choice but ultimately I went with this original version as my favourite due to that hint of Shibuya-kei in there. Plus, that video above with the manga characters being drawn in as the song is playing struck me as a true labour of love. I wouldn't have been surprised if the author got a misty-eyed watching it.
And perhaps some of the fans of "Konobi" even before the anime must have gotten a thrill at hearing the song performed in the show, thinking that it should have been used as either the opening or closing theme.
