Change colour of Rhino

Hey there,
I changed the colour of my rhino. However I couldn’t find everything. Where do I find the coulour of the curves in the menuoption and where do I find the coulour of the slider around the layers and properties and where can I find the option for the winows tab? I changed the winowds settings to dark mode and It works with my browser and everything else, however not with Rhino and Grashopper. ( For Grashopper cancvas I used Braunmanns component to change the coulour)
