Matching additive colors (RGB) to subtractive (CMYK, though even in mixed paints there are dozens of tints) feels fraught with peril.

More like "fundamentally impossible". Even ignoring the limited colorspaces due to choices of primary (i.e. the fact that no laser's color can be emitted by a screen), and assuming you calibrate your "white" (most screens are overbright these days), it turns out the pigments are really bad at "reflect exactly this pure-ish wavelength and absorb everything else", which is very frequently done by emitters.

  • Perhaps OP is offering a first approximation and not attempting an impossible platonic ideal?

Yeah the goal was simply to find the closest paints for specific RGB values from a reference image for a pointillism project I was working on.

I wasn’t trying to do the impossible and find the absolute perfect real-world color match. Just something close given the limited palette of acrylic paint brands I could find locally.
