Reply To: RE: Batch converting color swatches

HSB color swatches are literally the same as RGB swatches. Converting swatches to CMYK is prone to all kind of wonkiness because it’s not color managed… that is, you’re not specifying “which RGB” and “which CMYK” (there are many many RGBs and CMYKs). I generally would not convert color swatches to CMYK.

That said, if you want/need to, there’s a discussion and couple scripts here:
