The colours I get from the fp are quite pleasing. I used the Color Checker to make a custom preset. But I think the Merrill colours are better.

Are you able to make a custom preset using a Foveon image of the color checker?

If by "custom preset" we mean a file of type DCP, the answer is "yes".

first, to paraphrase Mrs Beeton*, download Adobe's DNG_Profile_Editor.

I had a DP2 image in DNG format which I had converted with the Adobe raw to DNG converter.

My shot looked like this:

When opened in the Editor, for each color patch, you can adjust the dots in the hue circle to be correct or even have more or less saturation, or even a different hue or lightness!

In the above, you can see that the red is bit off toward orange and a tad down on saturation. The arrow points to where it is and the little circle is where it should be.

After adjustment, you can save the above as a "recipe" file type .dcpr

or export it as a digital camera profile type .dcp

In RawTherapee you can select that profile as an input profile:

Off topic, RT can also take .icc/.icm files. I don't know about other apps.
