Neither is a good fit of describing colours in the real world, as they're dependent on the output device (in case of CMYK both the printer and the paper change the resulting colour). So a mapping of paints to CMYK or RGB would be rather meaningless.
- pavlov 10y agoThat's certainly true. But CMYK would be more useful because the commonly used CMYK spaces can represent a color gamut that's closer to the range of shades in the actual paints, whereas the commonly used RGB spaces are too limited. (A regular color printer can print a substantial range of colors that are aliased when represented in sRGB, i.e. you can't distinguish them on screen unless the preview is adjusted to compensate. This also happens the other way: many on-screen greens can't be printed without extra inks.)
