So I really wanted to implement a sharpening post effect for the game, but another thing I also had in mind was more saturation, since the game feels painterly, but due to atmospheric reasons seems to have been toned down but with the green channel still being quite strong.
So I've basicly run a tiny sharpen algorithm in the shader and toned up both the red and blue channel by about 5%
Warning: there's a chance this might conflict with your tastes.
custom experimental
Most original post effects removed, saturated, sharpen feature

Sharpness value can be adjusted with the softness slider in the video options.
You use it by checking the stylized lightning option in video settings.

THIS MODIFIED SHADER IS CURRENTLY BROKEN IN 1.07
(Will be looking into how to fix it, but until then just use the original ones with the patch or my custom one)
Install it by replacing the file with the same name in the
Elemental\Gfx\fx\fxo folder, where elemental is where your game is installed.
Make a copy of your old file so you're able to go back if you wish to.
Please report back with feedback here in this thread or if there's any problems.
