How can you convert a Pantone TPX colour code - such as 19-3921 TPX - to RGB?

Answer:
In general, you can't. Pantone codes are essentially lookup keys to a particular shade; they can't be "decoded" into RGB/HSV/whatever values.

Or rather, www.pantone.com has a great colour cross reference guide on their website. You can go to http://www.pantone.com/pages/pantone/color_xref.aspx and then select from the 3 menu sections:Pantone color guide> choose Pantone® Fashion + Home cotton for TPX colours; Color> you can search for your colour number using the search icon - without the TPX at the end is easier; for X-Ref Pantone Guide> just choose any option as they don't have RGB). Once you have done this you can click on the first colour swatch and it will give you the RGB and hex values. For 19-3921 TCX they recommend RGB 43;48;66 or Hex#2B3042. Hope this helps?
