Hey guys, I was working on game, and wanted to highlight a spot on the screen when something happens, I created a class to do this for me, and found a bit of code to draw the rectangle

static private Texture2D CreateRectangle(int width, int height, Color colori)
{
    Texture2D rectangleTexture = new Texture2D(game.GraphicsDevice, width, height, 1, TextureUsage.None,
    SurfaceFormat.Color);// create the rectangle texture, ,but it will have no color! lets fix that
    Color[] color = new Color[width * height];//set the color to the amount of pixels in the textures
    for (int i = 0; i < color.Length; i++)//loop through all the colors setting them to whatever values we want
    {
        color[i] = colori;
    }
    rectangleTexture.SetData(color);//set the color data on the texture
    return rectangleTexture;//return the texture
}

Problem is that the code above is called every update, (60 times a second), and it was not written with optimization in mind, I have no clue how else to write a code to do this though. It needs to be extremely fast (the code above freezes the game, which has only skeleton code right now).. Any suggestions. Note: Any new code would be great (WireFrame/Fill are both fine). I would like to be able to specify color.

Something to point in the right direction would be great, Thanks, Max
