Based on your description, it seems that you want to save a 1 to many relationship entities into database. like below:

 using (var context = new YourDbContext())  
    {  
        var car= new Car  
        {  
            Name = "My Dream Car",  
            Images= new List<Image>  
            {  
                new Image{ CarColor = "Blue" },  
                new Image{ CarColor = "Yellow" },  
                new Image{ CarColor = "Red" }  
            }  
        };  
      
        context.Cars.Add(car);  
        context.SaveChanges();  
    }
