Here’s a little stylization trick.
It kinda falls apart on anything besides rectangles; here’s some extra magic to fix that. With slightly different colors because I closed the file and wanted to play with it a little more.
The tilted rectangle on the lower right lacks this extra magic.
The fill is offset by enough to hide the ugly white edges; the stroke is the same width as that offset, and is offset by half its width. Making the stroke 0% opaque and turning on ‘Knockout Group’ makes it work as a built-in opacity mask for this shape – an ugly, but very useful hack. You could also just have some really thick outlines instead, or build a lot of clipping masks; both of those feel like Work to me and I’m generally allergic to that.
The rasterize effect is set to add 0 points around the path, which varies from my usual Document Raster Effect settings of adding about 35 points to give me room for most blurs I’m likely to use. You can also change the resolution, the tilted rectangle’s at a lower resolution than the rest of the shapes.
I might have to try doing some art with this look.
