Need Help. Change Color of Main Component by making color component . so when you click on one color e.g., red the main button component will be red and so on

I am Trying to make a theme based product prototype where i am using all the components to form a page instance. I want to make a theme e.g. red theme of my product with all buttons red. now if i manually change the colour of Main button to blue it will change all instances of the theme in prototype and lets call it blue theme. now i want to place a button/toggle in prototype for myself, to choose between red or blue which would change the colour of the main component hence changing the whole theme colour . this way i don’t have to make a copy of whole product with 10s of pages again in different design file with duplicate components.
