ditherin := Overlaying a repeating pattern of
disconnected pixels of one color over an image.
Dithering is used for creating artificial colors, adding texture, or tapering clusters into each other.
The lighter color pops out more. The recognising of the patterns is important, in a small space, dithering can seem like detail of the artwork or noise (which would be bad) instead of a fixed pattern.
It makes new artificial colors It allows tapering of clusters. Keep tapering clusters short as you don’t want to make a new cluster. pixel_art:
