Most likely they aren’t coloring it alone and they have a team of assistants which sometimes have a different coloring style from each other
Remember just because there are imperfections and differences doesn’t mean it’s AI. There is a reason why most mangas and manhwas have a team of assistants or even studios that work on them beside the main artist.
I agree with Lyricalbunny. And AI couldn't produce consistency in character drawing style.
Also, if you notice, a lot of k-webtoons use templates for their backgrounds and some detailed drawings. Hence, the inconsistencies. I once saw a video how artists do this by getting them from a different apps or websites. Similar to getting templates for 3d printing.
Like there was a tea set that went viral a few years back where it's all the same set in different webtoons or a castle you felt familiar turns out it was from another webtoon you read. They might also use readymade templates of certain movements then trace them to their own characters. This is common so they can produce their chapters fast on time for the scheduled updates and save money on assistants
Yes!
Artists have assistants and use 3D assets to help produce the chapters faster (but they refine it when it’s goes on print) otherwise they won’t be able to keep up with the tight deadlines
Also that short pink haired background character that almost every manhwa have (I started a game with myself to find her in every manhwa I read) it’s the same girl so it’s obviously some sort of a brush or something similar
generally webtoon main artists draw only the lineart/faces. And have assistant to lay in background , flat colors etc. and assets exist. Also webtoon canvases are long no way you can insert AI image there and not look weird because of the resizing, the line weight is pretty much consistent althroughout .
i really like the manhwa they're soo cute. but is it my impression or does the artist use a.i. to complete the art? the painting is not the same in different chapters and some lines are blurred. but i guess they only use it to color probably.
