Viewport solid mode objects color same as the collection they're in.

i thought it would be great if there is a function to set objects color same as the collection they're in in viewport. like random color mode in viewport, in more organized way.

i usually organize stuff with collections and change almost every single collection so i could easily see what those collections for by color. it would be really helpful if blender add this function

and maybe it would be great if there are more color options, or custom color for collection.
