HYB: inheritance of rims?

My favorite patterns are the light tops/dark falls with light rims (what
I started calling the 'umbrata' or shadow pattern, a play on words in
contrast to the luminatas).  I'm referring to the ones with sharp
margins to the rims, not the ones with ragged washes like HONKY TONK
BLUES or even ECSTATIC ECHO.

These mostly seem to come in four types - yellow pigmented ground with
anthocyanin "shadow" on the falls (variegatas), pink ground with
anthocyanin on the falls (?not sure what these might be called), white
ground with anthocyanin on the falls (amoenas with light rims), and
anthocyanin ground with more pigment on the falls (neglectas with light
rims).

I tried to go thru some pedigrees to sort out how these patterns are
inherited, but every pedigree I looked at involved so many seedlings, I
wasn't able to figure it out.

For the amoenas with rims - do the rims only occur on recessive
amoenas?  Or is the rim pattern inherited separate from white
standards?  Do the rims lack capacity to produce pigment or is it
inhibited?  Same question for dominant amoenas.

For the variegatas - is heredity of the pink ground & rims the same as
heredity of the yellow ground pattern?  Is anthocyanin inhibited in the
standards and rims or is it absent?  Is this one pattern (standards and
rims) or two (one for standards, one for rims)?

More or less the same questions for neglectas with rims.

In other words, are the light rims & tops recessive or dominant?  Or are
there other factors involved.  Do they usually stay together?

I'm not at all sure the answers would stick in my brain, and will
probably have to learn the hard way, but I am really curious.
