With NC 4.2.0, Tool Palette 2, Under White balance, you can set "Set Color Temperature", then select "Standard Flo", with the "Warm White 3000K", and adjust the slider down to 2610K (towards the cooler section).
2610K is abit too high for me, I typically go down to ~2200K using Adobe ACR or GIMP (w/ UFRAW)
