[C#] Calling a method of a child class on a parent object

Hey guys,

currently I am programming a game where the player has to steer a block through a tile-based level.

I have different kinds of "Tiles", e.g. "StartTiles", "NormalTiles" or "EndTiles". Therefore I have established a hirachy where Tile is the parent class and the other Tile types are children of that class, expanding it e.g. with an ID for a certain color that Tile should show.

In my game I want to set the ID for the color of the Tile to the current color of the block after it moved ontop of it.

However as there are different Tiles I use the parent class "Tile" as a parameter and then check exactly, what kind of Tile the block is ontop of. This means I am sure that this certain "Tile" is e.g. a "NormalTile".

The "NormalTile" class has a "SetColor()" method that is not present in the parent class. This is why I cannot call it in line 9, because this method is not in the Tile class.

Is there a fancy way to solve this issue without adding a specific virtual or abstract "SetColor()" method to the parent class "Tile"?

Here is the Code from the PlayerMovement script.

     public void AfterMove(Tile newPosTile)
     {
         switch (newPosTile.GetID())
         {
             case TileManager.NormalTile:
                 {
                     if (color > 0)
                     {
                         newPosTile.SetColor(ColorManager.colors[color]);
                     }
                 } break;
             default:
                 {
 
                 } break;
         }
         //canMove = true;
     }
