Thats a good thing!
About that “brown again” some days ago: there is a brown strip between the blue water and the bright yellow sand. Why?
Because that is how rendering works. I could ‘fix’ it, but it would only introduce a bunch of new bugs… I mean, there is no good fix. And this isn’t really that big of a deal. Every tile that connects to different tile type will have a ‘dirt’ strip in between, because there is really no other way to make it look nice.
If I was to start rendering strips based on connecting tile, that would make load of new bugs, which would look lot worse…

you would only need a couple of different colored strips. maybe even an edge for grass tiles and and edge for water tiles would cover most cases, and anything else could be a generic/brown edge.
rings any bells? 
the first version of the game had what you’re describing. To me, it didn’t look good. It was also way slower than current rendering method…
These sprites/textures are beautiful. That is all.
I would probably keep it down on the Add Noise filter, though. That’s a habit to always avoid doing.
