It's quiet hard to find manga since manhwa is the one who started being published colored...
Or if you think manhwas are also good for you, i recommend you to read some on Lezhim or Tapastic, most of their comic are colored~

Just place your tag in the search bar "Manhuas" or "Webtoon"
Doses anyone know any colored mangas ? I already read all the popular manhwa so it's realy hard to find any story with more than 40 chapter T-T
