I prefer comics with lots of colours. I grew up reading manga, lots of it even, but somehow I now enjoy web comics that splash lots of colours in their art. I am picky though, I need people to have a good art style before I dive in... not the prettiest trait of me, I know.
Can I show a comic I enjoy in terms of this? It's based on a novel, and they're a series of mini comics by @surenlicious. I love this art style, this artist has many in fact but she managed to select an art style for her comic that works for her. I know making comics are hard, and there are many styles to do one, but I like how she made hers. Its works in tandem with her written work.
Oh, and here's another one I like. Its...a bit much in terms of professional quality though and I certainly wouldn't force anyone to go WLOP's style, but I like this one too. It shows many many ways there are do to this in terms of fully rendered images, but I can only imagine what this level of quality might do to an artist.
