One thing I want to mention, and I'm not sure how good your camera is, Willa, but the front of house image that's from the listing is only 72 dpi (dots per inch--a leftover from print days), which means even when I try to increase that for better quality, it's sort of a hit or mess as to what the pixels will decide with details. If you don't know how to check it, and you have Windows, on an image that's stored on your computer, you can right click it and choose "Properties". Then look for a tab that says "details". If you scroll down a bit, you will see the dpi size. 72 dpi is often typical for average web images, even if the original had better quality because it makes the storage size of the image more ideal, as it is smaller as well.
The downside of that is it made it pretty impossible to do any "color washes" with the fill even in PS--it would fill half or more of the section I was focusing on. This took longer than expected because I had to manually outline bits and just do a straight fill, losing most detail like shadows. It's not nearly as complete as I planned to have ready after I had my late night snack. I think there is a way to use one of the PS tools that will grasp what the fill zone should be better, but the ones I'm used to and tried fared poorly. I just had the thought that I might be able to do a color replace with the lasso tool that would retain the details better.
I tried to follow your mentions as to what you were seeing where, but you may have a very different image in your head, and I may also have misunderstood some things you wrote. I'm not clear at all on the brick color (if any) from what you wrote, which could just be from my sleepy brain at the moment. My brain keeps blocking paint choices on the brick, saying "It's brick! No need for paint."
I did cut and paste your already painted door from your posting so that would be right, but did not paint the porch ceiling. I also did not do the door trim, nor the porch pillar and upper lattice. I wasn't sure if the trim was still the same color in the same photo I took the door from, or if you had since painted over that, so that's one reason I just left it the listing image color.
For reference, I took most porch terminology save trellis (no beaded rail) from the image below, but what I'm calling the beam might be the fascia, now that I'm looking at it again.
The color of the barge board detail scroll and the beveled rectangle are the same color (Georgetown Pink). The barge board itself is the Russet, and the recess the Burgundy.
The front of the post face bracket is Princeton Gold and the side is Richmond Gold. The scroll is Broadstreet Beige. I just realized after I posted this and looked at the other images again that are close ups of the post face brackets that the scroll I was seeing in close up was not a details, it seems to be an actual cut out and thus would not be painted. Drat.
The beam is Broadstreet Beige. I only did the inward bevels on the left rectangle of the beam inset, because I was thinking maybe I should do two variants (time again). I wasn't sure if you'd have preferred the Burgundy was the recess color which would mirror the barge board (I used Richmond Gold), and chosen a lighter for the face of that detail instead of the recess, or if you would like the contrast as I did it. If you like the "blue" behind the burst, that might be another place to feature it as a tie-in overall (mentioned below) if you don't want to cool down the beam using the blue there.
I did put the door color on the back of the sunburst detail of the barge board, but realize now I used a shadowed area to pull from, so it actually looks a bit closer to your Haint chip even though it is not. I also used the Russet color you said was closest to the color just under the roof in a section of that exact spot so you could get an idea of how off the colors are from your chips and the image. I also used the recess color for that strip in between to give it some texture so you have the weight you wanted, yet tried to give it a waistline, in a sense, to keep it from looking fat since you were concerned about that. You may prefer a lighter color, and I was going to do that further up so you could see the difference, but time wasn't on my side.
The low quality of the image made it very tricky without additional close ups to guess the designs on the barge board, so they're approximate. I did use your recess color behind the fish scale at its lowest point, then realized what time it was before I was about to start painting up in that area. I was planning to use it as a detail "waist" where the mini corbels are as well as the Russet to carry the barge board triangle frame.
I'm sorry I didn't get further with this, but I hope it helps a bit. Here's what I have so far, just based on the palette you posted and how I read your notes:
