Description
Is it possible in any way to reduce the distinct colors in an image with the result being visually similar as possible to the original?
I have found out that I can achieve this by setting the palette and bitdepth parameters when encoding to PNG format.
The question I am asking myself is whether this is also possible outside or before the encoding process and without committing to a certain image format. And if this is the case, is it also possible to reduce to any number of colors instead of fixed bit depths?
Thanks in advance.

Research direction
The issue does not name any files, tests, or entry points. Begin by reviewing how PNG palette and bitdepth parameters are exposed, then determine whether format-independent quantization and arbitrary color counts fit the binding; done would require an agreed API and documented behavior.
