What camera profile do you have selected in Lightroom and Camera RAW? Purple is a difficult color to reproduce accurately. I suggest you go to the camera calibration tab and select the same Camera profile you have selected in the camera. If you have not changed the camera profie the default for Lightroom and ACR is Adobe Standard.
The initial view you see is from the jpg in the RAW file, which is replaced by what Lightroom and ACR render using the Camera profile that is selected.
Awesome! Thank you for taking the time to reply, that was the fix. I was shooting on Faithful (0,0,0,0) which I assumed would be easy for the raw engine, but Lightroom was defaulted to Adobe Standard. I'll keep an eye on that in the future.
Most third party software does not read the in camera settings, I would say all but not sure about that. Lightroom and ACR only read the white balance data and uses defaults for everything else. You can save a new default that uses any of the available Camera profiles. You can also make the default ASA and/or camera serial number specific. I have mine ASA specific and have different noise settings for the various ASA.
