Drawing collision detection boxes

Question

So I have a TileSprite class that makes a TileSpriteobject with a collision box in it named bCollisionRect:

public TileSprite(Texture2D textureImage, Vector2 position, Point frameSize, Point currentFrame)
        : base (textureImage, position, frameSize, currentFrame)
{
    bCollisionRect = new Rectangle((int)position.X + collisionOffSet, (int)position.Y + collisionOffSet, frameSize.X - (collisionOffSet * 2), frameSize.Y - (collisionOffSet * 2));
}

But when I try to draw the collision boxes (to test collision detection), it doesn't draw the box. I tried using this:

public override void Draw(GameTime gameTime, SpriteBatch spriteBatch)
{
    // This is what I tried:
    spriteBatch.Draw(textureImage, bCollisionRect, Color.White);

    // base.Draw draws the texture (.Draw method from another abstract class)
    base.Draw(gameTime, spriteBatch);
}

I use this line of code in another class to draw my tiles (pure for testing!):

tilename.Draw(gameTime, spriteBatch);

Code to create a blank texture at runtime (after discussing with you via comments above):

Texture2D blankTexture = new Texture2D(GraphicsDevice, 1, 1, false, SurfaceFormat.Color);
Color[] color = new Color[1];
color[0] = Color.White;
blankTexture.SetData(color);

Then your draw call... specify a color if you want to tint it:

spriteBatch.Draw(blankTexture, bCollisionRect, Color.Red);
