What are those objects that you are talking about? If is about drawing environment elements (i.e. cursor, background) then you are allowed to choose different colors for those in ModelSpace, respectively PaperSpace.
Regarding the entities in drawing the only color behaving differently is white (7) that may be shown as black or white to get contrast from background. At least I’m not aware of something else.
If the question is addressing an exiting issue, since you are talking of yellow and white I suspect that this is only an optical illusion due to different backgrounds in MS / PS. Can you post screenshots of each tab?
