I might sound a bit confusing so just lmk if I need to clarify when reading this
My suggestion is to make the colors of each gamemode in the game selector match up with the titles on top of the npc and the platform so that they use the same/similar color (this not only includes the main games but also LTMS like Ghost Invasion, Block Drop etc)
Color of each gamemode in the selector
Color of the platform for each gamemode
Color of the titles of each gamemode
