The Kuler site does give HSV, RGB, CMYK, LAB, and HEX Color builds. But again, depending on your monitor's calibration that may or may not be an accurate color representation.
The first image above shows a swatch created from the Process Coated Color book and the next two show a swatch from the Solid Coated Color book. You must convert spot colors to process colors because any spot color placed in your document will generate an additional color separation (see below).
While a spot color may be desirable, picking swatch colors in this way can be an unwelcome surprise when you look at the separation preview.
The icons that designate whether a color is RGB, CMYK, or SPOT are quite clear (RGB at the top, CMYK in the middel and SPOT at the bottom). A SPOT can be generated from either the RGB or CMYK color space. To change a swatch from Spot to process (CMYK) you simply double click on the swatch to change the swatch options.
So while color palettes can be started in Kuler or can even be based on a photo, for consistency, they should be changed to Pantone colors to mitigate the disappointment caused by color mismatches.
