It is impossible to see what you have made from a screenshot.
To get your “artists impression” into KiCad, you can draw two different zones, the big yellow one and the smaller green one, and then give the green zone a higher priority.
The “zone outline which gets highlighted when i press the outline on the board outline” part is not drawn in KiCad. That zone boundary is calculated with B according to clearance settings.
You also have a relatively complex PCB with lots of zones. It’s probably a good idea to experiment a bit with zones and zone priorities on a simple PCB.
Attached is a PCB with some simple zones. The highlighted zone is defined by the PCB outline (and the pentagon around the PCB). This way it is immediately clear upon inspection if for example someting goes wrong with gerber generation). In the upper left corner there is a small keepout area, and just for fun I drew a triangular zone with a higher priority in the center of the PCB.
When the zones are shown not filled, there is no indication of the clearance between the “pentagon” and the “triangle” zones:
