This isn't only limited to those kind of genres. Pic related.
The funny shit is that Angolmois would look decent without those shitty filters on top of it. I watched the first episode of that one and It seemed pretty bland and boring, the background music was absolute shit that didn't even fit the setting, the OP and ED were also trash and those filters were the cherry on top:
>Filter texture on top of the show the whole time.
>Filter texture makes everything less saturated, nothing ever reaches black.
>The screen goes black.
>Goes a Dark greyish tone instead thanks to the texture filter.
>The filter's texture becomes completely visible.
It's about lazy and cheap ways of "improving" their shows. Probably since those studios are small they can't make the people doing the coloring put details into the actual backgrounds so they just put some filters on top of it to make do and hope nobody notices.
