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

- o11c 11mo agoMore 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.
- brookst 11mo agoPerhaps OP is offering a first approximation and not attempting an impossible platonic ideal?
- dotspencer 11mo agoYeah 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.
