Mitsuboshi Colors is a simple Slice of Life and Comedy manga about the misadventures of three little girls who form the "Colors gang". Every chapter is a different story with a few recurring characters centered around the protagonists' troubles and silly ideas.
Our trio of elementary school girls is often around their local park and interacts with a bunch of other characters in their city's neighborhood. They usually prank Saitou, go around solving cases, or play around with a few high school friends. There really is no much to the story, the trio simply reunites and plans some activity for the day and every day is a brand new adventure.
Regarding the characters. We have Sacchan, the super-energetic girl who loves to shout random stuff and usually has terrible ideas. Yui, the smart and shy girl who usually has the most logical ideas. And lastly, we have Kotoha, the girl who likes video games and loves to mock Sacchan. Their personalities aren't complex and they don't really develop but it's not really needed due to the episodic and simplistic formula of this story. The rest of the characters also have basic lines and present coherent and fun reactions when engaged by the Colors. Everyone's simple but charming.
The illustration is not excellent but it works for this kind of story. The panels and character designs are often basic but there are some really beautiful illustrations that bump the quality a little higher. While simple the girls' designs are still very pleasant to look at.
Overall Mitsuboshi Colors is a short and enjoyable Slice of Life manga with feels good and fun moments. It's pretty innocent and you don't really need to think, just enjoy it. There's also 0% fan service or sexualization so it's suitable for every reader. If you're looking for a fun story with innocent and fun characters you should read this. While I don't think it's as good as Yotsuba to, I still found this a very enjoyable read. It's also worth mentioning that the anime adaptation is equally fun and wholesome, so check it out!
