Hi all,
I released some filters that allow emulating a very basic chromatic aberration effect. They are available here with some explanations: < https://inkscape.org/da/~fabien.fellay/%E2%98%85chromatic-aberration-filters
They come with some animated examples as well: < https://inkscape.org/en/~fabien.fellay/%E2%98%85chromatic-aberration-rgb-cmy...

I later noticed that Inkscape already has similar filters available in the menu Filters > Color > Nudge RGB/CMY... However, the proposed filters here differ slightly regarding the alpha channel management and they do not flood the background with any color. If one just want to apply quickly a basic chromatic aberration effect, I think those filters may come in handy.
In the hope that someone will like them or find them useful.
Best regards, Fabien
