As requested i focused in your preference style of "Hollywood Regency" in an approached with light and dark colors in contrast.
Thanks to the natural light, I proposed a combination of light colors with some contrast with black in some areas as the living room, kitchen area and dining room.
Some of the contrast are from walls, carpets, fire place and furnitures that enhance the space with the gold color, emblematic combination for this style.
Chandelliers, some furnitures in vivid colors and neutral accesories complement the combination to aim a warm and cozy.
The room and studio are more conservative color contrast, but remain the style you want as a place to relax and concentrate.
i hope you like it my proposal!, if need more information i will happy to help you.
