It leaves open the question: are there any guidelines when choosing a Base Profile?.
The results obtained with the DNG PE / Chart Wizard may indeed show some unexpected dependencies.
From what we found the profiles vary significantly depending on:
1.) camera-exposure, +/- EV.
2.) the version of the DNG PE (1.0.0.39 vs. 1.0.0.46).
3.) the Base Profile used, sometimes at least.
Starting with
Adobe Standard as the Base Profile, when running the Chart Wizard the entry for the "Base Profile" in the Color Tables tab automatically changes from Adobe Standard to something named "ColorChecker". My understanding is that the Adobe Standard profile is cut down to the baseline matrix profile (equivalent to the former ACR 4.x profiles) before the Hue/Sat.-corrections from the Chart Wizard are build on it.
The first thing I do after running the Chart Wizard is to Clear all Color Adjustments and to export the resulting profile under the title "base matrix" (w/Base Tone Curve set to Camera Raw Default). Or, let’s call it "color palette # 1" in the sense suggested by the OP.
The Chart Wizard can then of course be launched again to add its Hue/Sat.-corrections. FWIW.
The results are the same as with the first run of the Chart Wizard above.
Walking along the same procedure but with Camera Standard as the Base Profile, we have seen that the results can be exactly the same as above with Adobe Standard (which means that the Camera Standard profile is cut down as well by the Chart Wizard to the same baseline matrix profile before the Hue/Sat.-corrections are build on it), but we also had cases where the results, the profiles and the logic were completely spoiled. I'm staying away from the
Camera Matching Profiles as a starting point to run the Chart Wizard.
