That being said, I think the slightly more muted schemes fit Pokemon's aesthetic better personally. Gen 5 in particular, I love it's color palettes. Sugimori's works tend to use a wide variety of colors, but they tend to be relatively unsaturated. Picrel is just a random example, you can see his earlier works were even less saturated with pretty dull colors when you look at them individually. His art got a liiiittle more saturated when he shifted to a more digital focus, but it still remained largely the same. In that sense, I think the shift fit better.
I think these tend to work best when there's more texture to them, like we can see with Gen 5's walkways and grass.
