tl;dr: Google "transitional interior design" and use elements you find, there.
This lady has caused me so much internal headache, I have become determined to figure her out.
When you google "transitional interior design," the images match Ramona's aesthetic preferences to a t. Lots of white/minimalism, coupled with dimensional texture like molding/trim (on both furniture and surfaces). There are jewel tone accents (I saw every images specifically with colors equivalent to Faded Sea Green 1). I haven't finished the latest house I'm working on for her (I actually have THREE PROPERTIES I've started EXPRESSLY to figure her out), but I'm attaching two rooms I've been working on. The living room is dope AF, imo, and I'm attaching the laundry/utility room, as well.
Key items I'm incorporating: clean, minimalism as the overall theme. Every essential room leans heavily on white. Brands: Homefort and Skadi for the "base" furniture, with a balance between contemporary/neutral minimalism and traditional/cozy. I include accent furniture from Valenti/"cozy"-tagged Homefort. Since the Faded Sea Green 1 is a jewel tone, and jewel tones in general contribute to "traditional" points for the buyer, I deviate from her color pallet with rich or faded indigo, pink, and the sea green in saturation 1 or 2, sometimes 3. I basically aim for whatever hits for me as "jewel tone."
Mood Anchors:
Rockfort Sink Cabinet (note the dimensional texture)
Byron and Wypocznik ottomans (minimalist; visual interest but simple shapes/lines)
Koivu/Ruusu/Garland seating (minimalist but visual interest in the swooping edges on the sides)
Madison molding to add more points to "traditional"
I don't know if this will work, but I am very hopeful. I'll provide updates if I succeed (or fail)!
