c# - Design Decision -- How to handle ImageList in a Game for good memory management

Question

I am in the process of building a game.

I have an object GamePiece (there will also be a Card Deck also)

public enum PieceColor
{
    Blue=0,
    Yellow,
    Red,
    Green
}

public class GamePiece : PictureBox
{
    PieceColor _color;
    public PieceColor Color {
        get {

            return _color;
        }
        set
        {
            _color = value;

            if (_color == PieceColor.Blue)
                this.Image = global::GameEntities.Properties.Resources.pieceBlue;
        }
    }

What I was thinking is putting four images, one of each color into a ImageList then the above line can be changed to

  this.Image = ImageList[(int)_color];

The problem I foresee with this is that I would be creating a ImageList for every GamePiece and that is a strain on memory.

A couple options would be

• Create a Static Class of ImageList objects, then have all pieces reference that static class
• Create one resource bitmap with all 4 pieces on it as one image, then use size manipulation to just show the one piece
• Leave the code the way it is and just have four different IF statements

So my questions are,

• Is one solution preferred over the other when it comes to managing memory with the same images used over and over?
• Is there any Design Patterns when it comes to display images, or any other related Game Concepts that I could study up on?

Thank you
